Code Overview, Compile and run
In our example we'll use both RGB LED and touch sensor, when pressing the touch sensor, we will randomly choose
one colour: red green or blue. Then we will turn the LED of the randomly chosen colour.
If we stop touching the touch sensor, the LED will turn off.
Compile the script by going into the samples directory and running: python3 touch.py
