The new Adafruit PyRuler comes with 4 capacitive touch pads. There are four colored leds above the pads. This makes the PyRuler perfect for implementing a Simon says game in CircuitPython. The libraries included in this project are for CircuitPython 4.x (bundle-4.x-mpy-20190815).
The PyRuler is a fully featured microcontroller board! Embedded in the end is a Trinket M0. For the pourpose of this project, the piezo buzzer is connected to the ground pin and the analog pin 3.
The code is well documented. You can see it here.
