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.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
