AT Command Mode of HC

AT Command Mode of HC

Having multiple bluetooth modules with the same name can be confusing. Sometimes it may require to change the default settings like baud rate, or master/slave role of the module. This guide shows how to enter AT command mode of HC05/HC 06 bluetooth module with the help of USB to TTL converter. Alternatively for HC 05, you can use an arduino board. Any other usb to ttl converter will do too./Arduino board, arduino uno used in this tutorial, other boards should work to.

3. It can be either HC05 or HC06. Both the modules are same in functionality except the pinout. Also HC05 can act as both master and slave whereas HC06 functions only as slave. It’s hard to differentiate between the two only by seeing. One probable way would be checking the back of the breakout board. If it has “JY MCU” written on the back, it’s probably a HC06. Mine has “ZS 040” written and it is a HC05. And the HC06 module I tested had a bluetooth sign behind with three pcb footprints(refer to figure2).

VCC: Indicated range is 3.6 to 6 volt. To be on safer side, you should connect it to 3.3 Volt.

GND: Ground.

RXD: Serial input pin.

TXD Serial output pin.

STATE: May or may not be connected to any pin. Supposedly outputs the Bluetooth connection status. This pin will not be needed.

Some of the breakout boards have EN pin or even WAKE UP pin instead of KEY pin. None of them seem to be connected to any pins of module. But that does not matter because we wouldn’t need them anyway.

Once you identified the module, now it’s time to enter the AT mode.

For HC05: Connect the Rx pin of the Bluetooth module to Tx pin of USB to TTL converter, and Tx pin of Bluetooth to Rx pin of converter. Also connect their ground but don’t connect the Vcc yet. First you’ll have to short the key pin with the Vcc. Connect key pin and Vcc together on breadboard, or any other way. After all other pins are connected, connect Vcc of bt module to USB to TTL converter’s Vcc. Now the led on the module will blink at the interval of 2 seconds. That means it has entered the AT mode. If the led blinks faster then AT mode was not entered. Disconnect Vcc, check your circuit and try again. the 34th pin. You can check that with the help of multimeter.

If you use an arduino uno, then connect Rx pin of the Bluetooth module to pin 11 of Arduino Uno(supposedly same for arduino mega), and Tx pin of Bluetooth to pin 10 of Arduino. Also connect key pin of module to pin 9 of arduino and ground to ground, but don’t connect the Vcc yet. You have to first power up the arduino, and then connect Vcc just like you did in case of USB to TTL converter.

For HC06: Just connect the Rx of module to Tx of usb ttl converter and Tx of module. Connect ground and Vcc. The module is in AT mode. Didn’t see that one coming, right? 😛 Turns out HC06 module is permanently configured to be slave and it is always in AT mode when not paired to any other device. So there is no confirmation led blinking that it is in AT mode like HC05 has.

I would like to say Jeannie is a dear friend of mine and the most amnazig photographer I have ever seen, I chose years ago to have Jeannie as my Bridesmaid in my wedding rather than my photographer. Although I don’t regret for a minute her being in my wedding because I love her dearly. I do regret not having her as my photographer, I went the cheap route and got burned, my photographer picked up and moved out of state after my wedding and I had to take him to court to get the pictures I ordered and paid for because he had lost my pictures. It all turned out well in the end I did get my pictures, but most were not what I has asked for and were not well done. So if I had to do it all again, Jeannie and Equinox Photography would and always will be my first choice for photographs. Jeannie you are amnazig.

Arts And Entertainment

Kerala, with its rich background of art and culture, has its own art forms which symbolises the outlook and life of Keralites. From the famous Kathakali, which is considered as the complete art form as it synthesis all that is best in the fields of drama, music and dance to the fascinating folk dances, which are the rhythmic impulses of a sensitive egalitarian society, Kerala’s arts are unique! The Yogi Bharatha wrote the famous Natya Shastra, the Science of Dance, in which he postulated that Musicology consists of the Eternal Triad of Drama, Dance and Music ( Geetham Natyam Thadha Nritham Trayam Sangeetham Uchyathe )!

Kathakali The Dance Drama of Kerala

Acting, dancing and Music these three arts constitute this dance drama. It is pantomime in which actors do not sing nor do they speak but interpret their emotions through highly sensitive medium of appropriate gestures, picturesque hand poses and vivid facial expressions, which is intelligible even to the layman ! Both dramatic and a dance art, Kathakali with predominance of histrionics, is considered as a complete art. It belongs to the imaginative form of Art and not the realistic, which is highlighted by Bharatha in his famous treatise !

This Master Art is Kerala’s very own, drawing its themes from the vast wealth of India’s Mythology and folklore. Ramanattom was created as a sort of rival to Krishnanattom and Kathakali evolved from Ramanattom into a complete art. It strictly follows the fundamentals and axioms laid down by Bharata, who was considered to be the father of Indian Classical Dances.

A high degree of control over body and muscle movements and facial expressions is called for, from the actor’s perspective. The performer is helped by vocal and percussion accompaniments and the theme is expounded by him through hand gestures known as Hasta Mudras , which are 25 in number. The best way to appreciate a Kathakali performance is to get the story explained to you in advance. This amazing evocative art has evolved into a package that weaves a tantalising spell today, combining chant, drama, dance, makeup, dress and gesture!
Arts And Entertainment

Prior to the genesis of this magnificent Art, there existed in Kerala different types of dance, drama and dance dramas. Arts like Chakyarkoothu, Koodiyattam and different dances associated with the cult of the Mother Goddess, such as Moodiyattu, Thiyyattom and Theyyattom, the socio religious and material dances like the Sastrakali and Ezhamattukali and the latterly evolved dance dramas like Krishnanattom and Ramanattom, were flourishing in Kerala prior to the advent of this Divine Art. You will find that characteristic features of these dances and dramas had been incorporated and assimilated by this Master Art

Magnificent archaic costumes, grand head gears and enchanting make ups characterise this majestic Dance Drama. It is perhaps the only dance form in India in which the masculine aspect of the dance is preserved in its pristine vigour.

All feelings are idealised and facially expressed with intense vividness and you will find that this compensates for the absence of the spoken word. All such facial expressions will harmonise and synchronise with the rhythm of the Dance and the musical melody.

Music is a very important ingredient and the Orchestra is composed of two vocal musicians, one keeping time with a resounding gong known as Chengala and the other with a pair of clanking cymbals known as Elethalam, a Chenda player and a Maddala player. Chenda is a cylindrical drum with a beautifully sweet sound while the Maddala appears as a big Mridanga.

All the characters of Kathakali are mythological and have different modes of makeup.

Adornment and attire are reduced to 5 types. They are

1) Pacha ( Green ) representing Noble and virtuous characters

2) Kathi ( Knife ) Unrighteous characters

3) Thadi ( Beard ) Demoniac characters

The most distinguished amongst the Thullal arts, Ottam Thullal was ingeniously devised by a master artist, Kunjan Nambiar. It is written that he was humiliated by a Chakyar, as Nambiar dozed off during a performance. In order to take revenge on his humiliation he wrote a poem depicting an episode from the epic Mahabharata in a never to fore metric and pattern rhythmic. A special kind of dance for its exposition was formulated. By innovative methods, humor and the enjoyableness of the programme, he attracted all audiences that had surrounded Chakyar. A new art was born and this was christened as “Ottam Thullal “.

The costumes and crown are copied from Kathakali, with variations. It is a solo dance with the artiste singing verses to the accompaniment of Mridanga with a refrain repeater singing behind. Duration of the programme is a couple of hours.

This is the oldest amongst the classical theatre arts and the solo dance is usually presented in Temples, to the accompaniment of Elathalam and Mizhavu. Beginning with an Invocation the Deity of the Temple, its narration is enlivened by the Thandava dance movements, facial expression and gestures according to the principles of Natya Shastra. Humour is abound in plentitude in this art and its themes are taken from India’s Epic Poetry ( Ramayana and Mahabharatha ).

A healthy diet is a well balanced diet. In order to feel well and strive towards our full physical potential and well being, we need to always consider what we ingest. What do we need, anyway, in order to function well?

Proteins: to help our bodies repair and grow tissues

Any weight loss diet should include all of these, if the diet wants to be a long term, healthy commitment rather than a sharp, short term weight loss method.

Keeping the balance right is very important. There are many diets and each different diet has slightly different ratios between the foods. One diet worth considering (and eventually tweaking) is the Mediterranean diet. The pyramid shows the ratios that this diet suggests. Feel free to read more information on the Mediterranean diet if you are interested or you want to try it out.

The Mediterranean diet is a great strong base for a healthy diet: however, it is important to keep in mind two main things.

That exercise is of the utmost importance when following any type of diet

That carbohydrates can and should be reduced if you want to lose weight and your exercise is low to moderate.

Having considered these two elements then, it is recommended to change the ratio of carbs and veggies to 1:1. Otherwise, veggies might also be the primary component of the diet and carbs could be cut down a bit.

To finish off with carbs: it is important to consider which type of carbs you are consuming. In fact,
Article Health and Fitness
grains and wholemeal bread is much healthier than white bread and if you are thinking of losing weight safely, you might want to consider these as alternatives to your normal loaf of white bread (either permanently or temporarily).

Do not forget to write down what you eat, especially when beginning a new diet: you might think you are having crisps rarely but maybe you are actually consuming a packet every other day. Crisps are a particularly easy food to pack and have without being fully conscious. Try to substitute them with carrots, or any other veggies. You might struggle at first, but in a few days you might notice the difference already.

Finally, remember: it is important to keep in mind that change does not happen overnight. If you keep on changing a small thing regarding your diet every week, you will gradually get in the habit of eating healthily. Balance is everything: if you have a bigger meal than normal one day, don’t despair and try to make up for it by cutting down the next day. Oh, and most importantly: don’t forget to drink water. Drinking loads is essential to keep your metabolism going!.

Arthritis Aids for Brushing Teeth

Arthritis Aids for Brushing Teeth

Good dental care is always important, but especially so if you have arthritis. The May June 2008 issue of the Arthritis Foundation’s Arthritis Today cautions that bacteria from the mouth may enter the bloodstream and contribute to inflammation and artery clogging. They recommend keeping your mouth clean, quoting Michael F. Just hold the base and the bristles automatically turn round so your joints don’t have to do the work of brushing.

The availability of refills is a consideration when buying electric toothbrushes. If purchasing an inexpensive one, buy plenty of refills at the same time so you will be sure to have them available. I really loved the smaller electric brush in the photo, which was inexpensive and purchased at a grocery store. When I went back to get refills, they were no longer made for this particular brush. I have since heard from a lot of people who have had similar experiences. So I bought the larger electric brush shown, which was a great deal more expensive but was made by a company committed to ongoing support of their products. I believe I would have been better off buying the less expensive brush and stocking up on refills at the time of purchase when they were still available.

Toothbrushes are manufactured with varying handle sizes, as shown in the photo above from small on the left to large on the right , with the Radius Original toothbrush at the very right still in the package. While I can’t hold a standard sized toothbrush because the small diameter handle requires too tight a grip, the larger handled ones are manageable for me.

When I got arthritis, my first approach was to enhance the handles of the toothbrushes I was using. This can be done using rubber bands or insulation made for copper pipes, or by plastic grips made for this purpose. While these solutions are good for pens and pencils, I wasn’t sure if I could adequately maintain the hygiene on a toothbrush over time so I switched to larger handled brushes instead.

Finding a toothbrush with a large enough handle could be frustrating. Models of toothbrushes seemed to change every time I went to the grocery store and no specific brand or product name consistently offered a large handle. I had to look through all the choices available in the store at the time I was ready to buy to find the largest handle.

Finally, I found a toothbrush that was perfect for me and I’ve been using it ever since. I purchased the huge handled Radius Original toothbrush at Whole Foods, but they are also available online. This brush is ergonomically designed, very easy to hold, and comes in both right handed and left handed versions as well as a child’s size. The handle is very large and formed to fit so a tight fisted grip is just not necessary.

The head is larger than a standard toothbrush, and I wasn’t sure I would like that. However, what I have found is that because the head of the brush is so big, there isn’t as much movement required to reach all my teeth. The Radius brush is not very heavy, even though it is significantly larger than a standard toothbrush.

The longer I have used this toothbrush, the more I like it. This is my favorite toothbrush because, even with my arthritic fingers, it is the easiest for me to use.

If you find yourself in a situation like that, then you may want to try.

1. Talking to your partner. This is the first person that you should talk to about the situation. See if he/she could talk to that family member about the problem. Sometimes all they need is to hear their loved one say “I appreciate your concern, but I’m happy with the person that I’m with”.

2. Talking to the person in the family that’s giving you problems. Express to that family member how you feel. Sometimes they may be mean or critical because they don’t want to see the person that you’re involved with get hurt emotionally. If that’s the case then you can let them know how much you care for your partner and you want to have a loving and lasting relationship.

Whatever you decide to do, make sure that you express how you feel as soon as the problems occur. A lack or delay of communication can cause unnecessary problems and extra stress that could be avoided.

Are Travel Agents A Thing Of The Past

Are Travel Agents A Thing Of The Past

In the past, before the advent of the Internet, it has largely been too time consuming or too expensive for the average consumer to deal directly with the travel operator and personally arrange every aspect of their holiday. Travel agents became a trusted and speedy medium via which the holiday consumer could book a ‘package’ that would otherwise be impossible for the independent consumer to find.

The role of the travel agent includes three key tasks:

These three tasks have been lampooned by the information and facilities provided on the Internet. Consumers have recently realised that it is possible to research their planned holiday fully online. Users can find out about specific regional information at the click of a mouse. Small local hotels, specific local attractions and regional tours can be researched with ease before a booking is considered.

In the early years of the Internet, consumers tended not to trust booking online. It was perceived that parting with credit card details over the Internet was not a secure method of payment. Users instead tended to research everything they wanted to know before hand and then contact their travel agent either face to face or over the phone to book their holiday package.

The Internet offers an effective means for developing a single and sustainable electronic infrastructure for information gathering and business transactions for both travellers and suppliers. It is an ideal method for people to source information on travel. It is therefore essential for travel related Websites to offer useful, pertinent and easy to find information alongside a booking facility if appropriate. The Internet can be used to fully research a destination, book all aspects of the holiday including travel and communicate others who have the same ideas or have been through similar experiences. It gives travellers an excellent opportunity to compare and contrast everything on offer before they make a purchase.

The information available online is continually being reformatted and presented in a more logical, easy to use and read format. The volume of consumers that rely on this information to make travel related decisions will therefore continue to rise. In addition, features and benefits of using the Internet to research and book holidays are improving and being added to all the time. For example, consumers no longer have to receive printed tickets from the travel operator. They simply print out any information that they require themselves after they receive it automatically via email.

The Internet has meant that people can now easily plan trips for themselves. This has not only opened up a greater amount of discounts available to the general public, but also given people the fun and enjoyment of planning and booking their own trips.

Are travel agents a thing of the past? The future isn’t looking too rosy for them. They might perhaps retain their presence in certain specialist markets, where they can offer a unique service to individual market segments but if you’re a ‘love all, serve all’ travel agent you’ve probably seen your income levels drop significantly over the last few years.

To explain RFID for the layperson, we can use a key and lock analogy. Instead of the key having a unique pattern, RFID keys hold a series of unique numbers which are read by the lock. It is up to our Arduino sketch to determine what happens when the number is read by the lock. The key is the tag, card or other small device we carry around or have in our vehicles. We will be using a passive key, which is an integrated circuit and a small aerial. This uses power from a magnetic field associated with the lock. To continue with the analogy our lock is a small circuit board and a loop aerial. This has the capability to read the data on the IC of our key,

and some locks can even write data to keys. Our reader (lock) example is show in the image above.

These readers are quite small and inexpensive however the catch is that the loop aerial is somewhat fragile. You will need:

Solar power have the advantage of being less maintenance and pollution free but their main drawbacks is high fabrication cost, low energy conversion efficiency. Since solar panels still have relatively low conversion efficiency, the overall system cost can be reduced using a efficient solar charge controller which can extract the maximum possible power from the panel . As the input voltage from the solar panel rises, the charge controller regulates the charge to the batteries preventing any over charging. PWM3. MPPTThe most basic charge controller(ON/OFF type) simply monitors the battery voltage and opens the circuit,
stopping the charging, when the battery voltage rises to a certain level.What is PWM:Pulse Width Modulation (PWM) is the most effective means to achieve constant voltage battery charging by adjusting the duty ratio of the switches ( MOSFET ). In PWM charge controller, the current from the solar panel tapers according to the battery’s condition and recharging needs. When a battery voltage reaches the regulation set point, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery,
yet the charging continues to return the maximum amount of energy to the battery in the shortest time.
