micro:bit OLED compass #microbit @MSMakeCode @blogmywiki

128 x 64 pixel OLED displays are inexpensive and provide a great way to augment micro:bit projects. They’re easy to wire up using a breakout board and 4 female-to-female jumper wires.

There are lots of different ways of driving OLED displays from a micro:bit. I’ll do a round-up of them all soon, but here I experimented with using a MakeCode extension for a 4Tronix robot, the Bitbot, which happens to include some quite nice blocks for writing text and drawing shapes on an OLED display.

As well as showing the compass bearing and current temperatures as numbers, it also draws a line to show which way North is – just like a compass needle.
