|Step_Title=<translate><!--T:4--> Install Arduino IDE</translate>
|Step_Content=<translate><!--T:5-->
You will need to use Arduino IDE to code and upload the firmware onto your ESP32 board.

<!--T:6-->
Download the software by visiting [https://www.arduino.cc/en/Main/Software? Arduino IDE] > Scroll down until you see the “Download the Arduino IDE” section and choose the version based upon your operating system (e.g. If you have Windows 7, choose “Windows Installer” / if you have Windows 10, choose “Windows app”) > On the next page choose “Just download” and run the installation files.</translate>

|Step_Title=<translate><!--T:7--> Prepare the ESP32 board on your computer</translate>
|Step_Content=<translate><!--T:8-->
Follow the [https://github.com/espressif/arduino-esp32/blob/master/README.md#installation-instructions instructions provided on GitHub] for your Operating System. For example, if you have Windows 7 or 10, choose “Instructions for Windows” / if you have a MacBook, choose “Instructions for Mac”

<!--T:9-->
For the “Instructions for Windows” section, you can ignore the following step:</translate>

|Step_Title=<translate><!--T:10--> Check that the board is correctly configured</translate>
|Step_Content=<translate><!--T:11-->
Launch Arduino IDE and select “ESP32 Dev Module” from the Tools menu > Board.

<!--T:12-->
Fetch the Blink example from File > Examples > 01.Basics > Blink.

<!--T:13-->
write int LED_BUILTIN = 2; at the top of the code

<!--T:14-->
/*

<!--T:15-->
 ESP 32 Blink

<!--T:16-->
 Turns on an LED on for one second, then off for one second, repeatedly.

<!--T:17-->
 The ESP32 has an internal blue LED at D2 (GPIO 02)

int LED_BUILTIN = 2;

<!--T:20-->
void setup() 

<!--T:21-->
{

<!--T:22-->
 pinMode(LED_BUILTIN, OUTPUT);

<!--T:23-->
}

<!--T:24-->
void loop() 

<!--T:25-->
{

<!--T:26-->
 digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)

<!--T:27-->
 delay(1000);                       // wait for a second

<!--T:28-->
 digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW

<!--T:29-->
 delay(1000);                       // wait for a second

<!--T:30-->
}

<!--T:31-->
Finally, upload the code by using the right arrow (→) button at the top right corner of the window, by choosing Sketch > Upload or by pressing Ctrl+U on the keyboard.</translate>

|Step_Title=<translate><!--T:32--> Wiring the LED and the touch sensor to the ESP32</translate>
|Step_Content=<translate><!--T:33-->
We will connect an LED to the board so that we will know when the tail actually gets touched.

<!--T:34-->
Connect a male/female jumper wire to D4 on the board. D4 is by default connected to the internal touch sensor.

<!--T:35-->
Connect D2 (by default connected to the board’s internal LED) to the positive leg of the external LED, using a male to female jumper wire.

<!--T:36-->
Connect the negative leg of the LED to GND on the board, using a male/female jumper wire.

<!--T:37-->
If needed, use some tape to secure the jumper wires to the LED.</translate>

The wooden pet needs to be laser cut. You can download the cutting pattern for laser cutter from [https://drive.google.com/file/d/1AHXk4zxDN0U7YNiMKVyBzvakh8pY8MH9/view?usp=sharing here].

<!--T:40-->
Place all the parts inside the pet, and connect the internal touch sensor to the aluminum tail.</translate>

|Step_Title=<translate><!--T:41--> Programming on tuniot</translate>
|Step_Content=<translate><!--T:42-->
Let’s create a program that registers the values recorded by the touch sensor and publishes them online.

<!--T:43-->
For that we need to reach: http://easycoding.tn/esp32/demos/code/

<!--T:44-->
Choose the appropriate blocks to create the code displayed below.

<!--T:45-->
Complete the fields “ssid” and “password” with the name of your wifiwi-fi connection and its password respectively.

<!--T:46-->
The “User Name” and “Key” are available here (just click on View AIO Key).</translate>

To upload the code on Arduino IDE, click on the “Copy Arduino code into clipboard” button.

<!--T:51-->
then paste the code onto Arduino IDE, and upload it to the ESP32.

<!--T:52-->
If you click on Serial Monitor (top right of the Arduino IDE screen, below the “X” button), you should see the values recorded by the touch sensor.

<!--T:53-->
It means that your ESP32 is connected to the internet, and that it’s sending the value recorded by the internal touch sensor on-line, on https://adafruit.io.</translate>
