DIY Electronic Piano Circuit on Breadboard | 555 Timer Project #9

Title:

Description:

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. Explanation of how the circuit works is also included in the video.

Components Required:
* 555 IC
* 8 Ohm Speaker
* Momentary Push Button Switches x 6
* Capacitors: 100nF, 10uF
* Resistors: 6 x 1K, 4.7K
* Breadboard
* Few Breadboard Connectors
* (5-9)V of Power Supply

This circuit uses 555 timer IC in astable mode to generate continuous clock pulses. These pulses are passed into a 8-Ohm speaker and it generates audio with different tones depending on the frequency of clock pulse. In order to understand how 555 timer IC works in astable mode, you can go through the explanation part of this video: https://youtu.be/TTQnhIkw4Bk
