Wooden pet that post a message on your own Facebook timeline.
In this tutorial we will create a wooden pet that connects with Facebook. It will post a message of your choice on your own timeline whenever its tail is touched.
Once you ve set up an account on adafruit.io, go on creating a new Feed.
Create a new feed and name it, for example, “touchsensor”.
Follow the instructions provided on github for your OS
If you have troubles following the instructions for windows, you may find some help below.
To find the Sketch directory, click File > Preferences, on arduino IDE.
The process of cloning existing repository may take a tomatically.
Launch Arduino IDE. Go to Tools > Board and select “ESP32 Dev Module”.
Fetch the Blink example on File > Examples > Basics > Blink.
Upload the code by clicking on the arrow pointing to the right.
We will connect an Led to the board so that we will know when the tail actually gets touched.
Connect a male/female jumper wire to D4 of the board. D4 is by default connected to the internal touch sensor.
Connect D2 (by default connected to the board’s internal led) to the positive leg of the Led, using a male to female jumper wire.
Connect the negative leg of the Led to GND on the board, using a male/female jumper wire.
If needed, use some tape to secure the jumper wires to the Led.
The Wooden pet needs to be laser cut. Download the cutting pattern for laser cutter : sheepboxconnected.svg
Complete the fields “ssid” and “password” with the name of your wi-fi connection and its password respectively
The “User Name” and “Key” are available on your adafruit.io page.
Sketch > Include Library > Manage Libraries…
To upload the code on Arduino IDE, click on the “copy arduino code into clipboard” button.
Then paste the code onto Arduino IDE, and upload it to the ESP32.
if you click on Serial Monitor (top right of the Arduino IDE screen), you should see the value recorded by the touch sensor (see image below).
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 adafruit.io
Click on My Applets.
Choose New Applet.
Click on THIS (see image below).
Search for Adafruit.
Choose Monitor a feed on Adafruit IO.
Configure it as follows (see image below)
And Click on Create trigger.
Click on THAT
Choose Create a status message.
Type your message and click on Create action.
In this case, the message that will be posted on your Facebook timeline is “Don’t touch my tail!”
