# This example allows you to test each key and LED in turn
|
||
|
|
# 1. At startup all LEDs should be white
|
||
|
|
# 2. Press a key and it will turn blue
|
||
|
|
# 3. Release that key and it will turn white
|
||
|
|
# 4. *Hold* a key and it will turn red
|
||
|
|
# 5. Release a *held* key and it will turn green.
|
||
|
|
# If you can turn all your keys blue -> red -> green, they're good!
|
||
|
|
|
||
|
|
# Drop the keybow2040.py file into your `lib` folder on your `CIRCUITPY` drive.
