Description

This melody organ circuit generates 25 different tones by touching the conductive electrodes with the metal probe. The tones range from low to high. The LM555 creates the 25 basic tones and a transistor oscillator provides a vibrato effect. The kit is supplied with an 8 Ohm 0.25W speaker.

This is a great project to learn electronic assembly and also electronic principals. Many schools and training facilities use this kit for learning soldering and electronic component identification. 

Appropriate for Middleschool and older students.
