DIY Electronic Piano Circuit using 555 Timer IC | English Subtitles| Top School Projects.

Описание

A tutorial on how to make an Electronic Piano circuit using 555 timer IC and a few other electronics components. This circuit consists of a number of push button switches (similar to different keys in a piano) which, when pressed, produce sounds with different tones via a speaker.

The frequency of the output tones can also be fine tuned by calculating the precise values of resistors to use. Formula for calculating the frequency is included in the explanation section of this tutorial.

Watch the video above for detailed step by step instructions on how to build this circuit. Explanation of how the circuit works is also included in the video.
