Rain drop effect NE555 DIY Kit

Posted on June 15, 2020June 15, 2020 by kitstvcom

This is yet again a very simple astable multivibrator circuit using NE555. The circuit produces a sound that somewhat sounds like a raindrop. This is a very basic electronic kit project for electronics beginners and hobbyists. Anyone with basic electronics and soldering skills can build this easily.

The circuit is an astable mode timer. The output frequency of the NE555 varies with the change in resistance of the photoresistor. When you block the light falling on the photoresistor, its resistance drops and that contributes to the change in frequency of NE555.
