immerbell

A tinkerer's wireless doorbell conversion

Similar projects worth following
Had to remove the wire that runs from the doorbell button to the bell itself. This is a simple project that aims to restore this connection over wireless network.

Using a pair of Raspberry Pi Pico microcontrollers, power supplies and relays, my solution was to control the bell from software that I wrote in Rust. This way, I was also able to start learning Embassy, a framework that allows you to write asynchronous code for embedded devices, which was my other goal.
