Of course, the Arduino board has to have a removable chip.
If you have a UNO board for exemple, if you remove the microcontroleur you can use the RX, TX, GND, 3.3V Pin to reprogram the ESP8266. You can find one in a special device like a FTDI board but you also have one in every Arduino Board that you can program over USB (On the UNO the FTDI has been replaced by a 32u2, but it worked exactly the same).
The most important component for programming is a Serial to USB converter like the FTDI FT232RL. There are many ways to program your ESP8266 board : You need to add the following components if you want to build it :
On the second part of this Instructable, I explain how to make a more reliable programmer.
Arduino board with removable chip like UNO (but not the SMD version!). FTDI basic board and a 3.3V power supply (min 500 mA). To program your device, you gonna need a few wires and : It forward the mail between the device and your mail account (the Free version is limited to 20 mails a day).
Battery 6.95$ In a bigger device you could use a CR2032 to multiply the autonomy by 2.3 or even this bigger Battery to multiply by 9 !. LED 0.35$Resistor 0.02$ (I used a flat top 3mm bought on Ebay). Button 0.5$ choose the one fit the best in your model, I used a "pushbutton 12*12*8cm". You actually don't really need it if you don't want to change a lot of thing on the code. Plus, it's now Arduino compatible!Īs i was adding program inside the ESP8266 100 times a day, I decided to also build a user-friendly programmer. The ESP8266 is a great tool for any microcontroleur/wifi application today. A standard 110 mA battery should work more than 2 months, a CR2032 for 5 months and a 1000mA for 2 years.įor this project, i used the cheapest and smallest components I could find. All the components are easy to find and to adapt if you want to make a new design by yourself. The electronic cost is around 8$ which is affordable for most people and you have to add a battery of your choice. A big community is now using this device and it recently became Arduino IDE compatible. If you want to make a wifi connected device today, the ESP8266 board is a very good choice! It costs only a few dollars and it has its own 32bit reprogrammable micro-controller (The Atmega328p on the Arduino UNO is only 8bits). The price is also a very important question. As some aged people are trembling a lot, the button is quite big, which makes it easier to press. As a result, the device is 2.5 * 1.5 * 1 cm in size ( 1*0.6*0.4 inch) which can be easily integrated to bracelets, necklaces or clothes. Therefore, it was important to reduce dramatically the size and the weight. The device has to be easy to wear and to integrate. As a lot of people receive Email on their phone and check their phone 30 times a day (like me :s), the emergency can be quickly followed by calling the person or knocking at the door. The device will connect to the internet box and send an Email to a pre-entered Email address. A LED turn on to confirm the emergency is activated. If a person is in distress for a reason, he or she has to press a simple button on the device. Most of them were very happy to help and even asked to add their Email address to the list so they can quickly help in an emergency. As a lot of old age people don't actually have a wifi, i decided to ask the neighbors for wifi access. So I decided to build a wifi connected device, which make things easy to communicate with the external world. In most apartments today, you can easily reach 10 or 20 wifi connections.
