Uses an SVG of the microbit from https://github.com/microbit-foundation/microbit-svg and a python script to create images of the microbit showing arbitrary pixel displays.
Credit to https://github.com/microbit-foundation/microbit-svg for the original SVG.
To use, simply edit the config.txt file and run the python script. It will generate an output.svg file.
Put the brightnesses in the following order:
0 5 10 15 20
1 6 11 16 21
2 7 12 17 22
3 8 13 18 23
4 9 14 19 24
