This simple project utilizes the built-in compass of the Micro:bit and the MicroPython Speech synthesis module to make a compass that tell you the direction you are facing.
The parts list for the talking compass is a Micro:bit with its battery pack, an Amp:Bit by Proto-PIC and a speaker. The Microbit is inserted into the Amp:bit and the speaker is connected to the terminals on the Amp:Bit. Just that easy. Instead of the Amp:Bit you could use a small mono audio amplifier, like this one from Adafruit.
The software is written in Micropython. The code is over at Hackster.io
