Proposed Features for the 1Keyer

designed to make use of inexpensive Arduino Micro/Nano modules for ease of construction and low cost.
small but flexible software, written to provide a flexible framework for future experimentation.
implements an iambic keyboard controller. Implement both "mode A" and "mode B", with user controlled adjustable speed via a potentiometer.
serial interface which implements two different use cases:
- data read from the serial data port is automatically sent via morse code
- characters keyed with the paddle are also translated into ASCII and sent out the serial port
keying output to control key a radio transmitter
a sidetone output, which is a 700Hz audio to provide audio feedback that the keyer is working
Fits in just 1K of Flash, to make it an entry in the Hackaday 1K Code Contest!
