A teeny circuitpython script that makes your mouse shake to keep your PC awake.
This was created and used on an Adafruit Trinket M0, a low cost SAMD21 development board that I absolutely adore.
Plug the device in with this main loaded up, and every few seconds your mouse will shake! You can edit the settings at the top of the main.py to adjust how often or how far it shakes easily. As well, tapping on pin 3 with your finger will enable/disable the shake. (It uses the capacitive touch of the pin, so it can be a little tricky to get the feel for. The RGB LED will go through a nice color wheel while it's active, and pulse red while it's not. The other led lights up when you're activiating the touch on pin 3.
