1. N1AW Arduino Keyer Objectives: CW keyer with accurate speed setting. Report speed using audible Morse. Change speed easily. Get familiar with Arduino

2. Standard Arduino

3. Freeduino RBBB

4. USB Interface for RBBB

5. RBBB mounts on breadboard

6. Complete Keyer Connectors: Stereo jack for paddles Phono jack for key line to xmtr

7. Operation This version: initial speed 20 wpm. Could save last speed to initialize at next startup On startup speed reported as Morse Paddles generate dits and dahs Control switch (push button) reports speed Control + dit paddle → decrease speed Control + dah paddle → increase speed Hear 2 dits for each 1 wpm + or - Xmtr not keyed for control operations
