Getting Started with the micro:bit

6 Interfacing with the GPIO Pins

Now that you’re familiar with the micro:bit board and its onboard parts, we’ll look at interfacing with the GPIO pins on the edge of the board. There are several ways to connect to them, the most basic way involving alligator clips and banana plugs.

As you’ve probably noticed, several of the pins on the edge of the micro:bit are both larger than the other pins and are also connected to holes in the board. This enables you to attach either alligator clips (Figure 6-1) or banana plugs (Figure 6-2) to the board for basic interaction. I won’t go into the specifics—readers are more ...
