Hi
I`ve done a morse decoder-sender-key-sketch.
I use same sketch in 2 different units. Both works for sending and reciving.
You type the morse-code in a button and get the letter in both your own LCD and the reciver-LCD.
The buzzer sounds when you push the botton(send).
On the reciving unit the buzzer bipps the morse code.
The Morse decoder itself is not mine creation. I just added LCD and RF to it.
