Toy Organ Kit

Forrest Mims

The Toy Organ kit is a music maker based on a simple 555 timer circuit. With the addition of a resistor, some capacitors and some buttons, you can generate several different tones. Add a few potentiometers and you can control the volume and the pitch of the note. Even more, when you press several buttons at the same time, another unique tone is generated.
