Break a circuit on a alarm clock

@madd444 I agree that you can build it from scratch. I already told you the materials in my previous post.

See this for explanation of SSR:

The module you posted is an Optocoupler isolation board, which I don't know how to use. I'll see how it works and then tell you :slight_smile:.

You can use a SSR instead of the electromechanical relay that I showed you in the previous post.

An SSR module looks something like this: https://images.app.goo.gl/3XoRT8iNfHZBcdKw6
