The Piantor Keyboard is a beginner-friendly, easy-to-solder, 42-key or 36-key, diodeless, low profile aggressive column staggered, hotswappable and non-hotswappable, programmable ergonomic mechanical split keyboard powered by Raspberry Pi Pico or other compatible RP2040 boards. It is based on the Cantor Keyboard.
Is there possibility to use built-in led of pico to show current layer?
For example:
left off + right off -> 0 layer left off + right on -> 1 layer left on + right off -> 2 layer left on + right on -> 3 layer ...
If go further, we also can use blinking led and continue list of layers
