Description

A simple and fun project for beginners: The 2-Tone Door Bell DIY Soldering Kit with NE555.

A handful of components need to be assembled on a circuit board size of just 28 x 25mm. With a battery (4-7V recommended) and the speaker connected, the 2-Tone Door Bell will create the typical “ding-song” sound pattern of ancient, electro-mechanical doorbells.
