Ding dong doorbell kit - PCB only

It has been said that you are not a true electronics enthusiast unless you have made a dong-dong doorbell. Well, here’s a simple kit that does exactly that!

Many electronics DIYers make a simple ding-dong doorbell as one of their first projects, often using a common 555 IC, but they usually sound terrible. But, there is a better way, or at least a different way that produces a nicer sounding doorbell.

This is the bare PCB only, no components are provided. You will need an M602 IC for this PCB, see the M602 IC here.

We no longer include printed instructions with our kits, instructions can be downloaded here.
