@ProjectsWithRed Жыл бұрын
Technically you can replace the Attiny88 with any micro-controller (MC), however, you need to be mindful of the current consumption of the MC. The Attiny88 was chosen because it has very low current consumption hence why it can be used for a very long time with a small battery in the relatively small housing. If your chosen MC has a high current consumption, consider using a bigger battery, but you will probably have to make the keyboard housing bigger to accommodate the space required for the bigger battery, or use the same battery but you will have to change the battery more frequently.

You can connect all buttons to Vcc and through different resistors to the same ADC pin, then in the code you can make checks for different ranges of ADC values. I haven't tried this and its not a very reliable way, but it should work.
