Automate real devices with the Pimoroni Automation:bit using drag and drop makecode in the browser. It's a great way for kids aged 7+ to build robust projects, using the micro:bit's built-in sensors and buttons - you can even connect external controls using the screw in wire terminals.
Analog or digital inputs with no breadboard wires to fall out - or soldering required!
The relay can be wired to low-voltage devices that use less than 24V e.g. battery operated lamps, fans, toys, or whatever you can think of. Then slide the microbit out quickly and easily to swap between projects!
