Electronics Organ - Solder (with PCB)
Introduction
This is an ingenious little device that is an ideal introduction to electronics. It is fun to build and more fun to play with!
You touch the end of probe or wire (P) on one of the pins (A – M) and a fixed frequency tone will greet you. This simple device can generate up to thirteen tones.
Imagine yourself using it to entertain your friends with familiar nursery rhymes tunes such as “Mary had a little lamb” and “Twinkle, twinkle little star”. Isn’t it great?
