Here is a rundown of the different ways you can connect wires to the micro:bit. This is something I’ve spent a long time working out and trying out different techniques.
THROUGH THE HOLES
The micro:bit has 5 holes representing 5 pins: 3 data pins, ground and 3V. You can wrap wires and thread through the holes and around the edge of the micro:bit. You could secure with some electrical tape.
Pros: Simples! No extra skill or kit required
Cons: For projects that move, the tape never holds onto the wire/thread. Moving wire/thread also risks touching other pins and shorting the micro:bit. It would be tricky to attach more than 1 wire to 1 pin.
Cheap and cheerful. Crocodile clips can be clipped onto the holes of the micro:bit. If you need a wire on the other end you could always chop off the crocodile’s head!
Top Tip: Pass the croc clip jaw through the hole for better grip!
Pros: Cheap, easy to use, no extra skills needed to attach
Cons: Not very stable. When moved they can lose connection or touch other parts of the board. Can only attach a limited number of crocodile clips to each pin. Can only use the 5 basic pins. If you pass the jaw through the hole it makes the whole setup a lot taller.
