Once you’ve selected a schematic, the real fun begins: making the keyer truly your own. This open-source project gives you the freedom to decide exactly what goes into your build and how it behaves.

Connect Pin 5 (Collector) of the optoisolator to the positive tip of your rig's key jack. Connect Pin 4 (Emitter) to the ground sleeve of the key jack. 4. Sidetone and Audio Output

Arduino Mega 2560 or Arduino Nano (ATMega328P based). Display: 16x2 or 20x4 I2C LCD display. Speed Control: Potentiometer. Input/Output:

to handle advanced features like LCD displays and large memory banks. Keying Output

Never connect your Arduino pins directly to a radio's keying jack. Vintage rigs carry lethal voltages, and even modern rigs can experience ground loops. Use an optoisolator (such as the 4N25 or PC817) to completely isolate the microcontroller from the transceiver.

Built-in capability to decode incoming CW from a receiver.

Updated sidetone circuit with a simple R/C filter to smooth out those "fierce" harmonics often found in basic piezo setups. Modular Inputs:

By combining these resources with the knowledge and tips presented in this article, you'll be well on your way to a successful K3NG keyer schematic repack.
