This video shows how to make the bread circuit for 555 timer based Door Bell.
Full Project :
The schematic was reverse engineered by Julian Ilett from a kit.
I was inspired by his video and made this project on a breadboard.Then I make a PCB for the same circuit.
You can download the PCB from the following link
