Shield for relay



Product Description

Control & monitor your world with automation:bit Add-On for the BBC micro:bit! It's tolerant of up to 24V, with analog and digital inputs, outputs, and a relay, so it's ideal for automating low-voltage systems in your home.

Just slot in your micro:bit, then code automation:bit with the block-based Microsoft MakeCode editor. Hook up buttons to the inputs, use the built-in buttons on micro:bit, or the light-sensing capability of the LED matrix to control devices connected to automation:bit.
