A CW/morse code paddle built with an atmega32u4 processor.
I needed a paddle to practice morse code with, so I built one with a AVR chip, and some paper clips. Code should be fairly self-explanitory. Pins 2
and 3
are paddle inputs (pull up), and pin 4
is the voltage output.
- Re-write this to run without the Arduino library. I don't need any fancy features, so plain AVR code should be fine. Maybe switch to using an ATTiny in the process
