Week 10: Output Devices
Digital level
The idea
A 2-axis digital level.
Charlieplexing
To help get my head around Charlieplexing I used some creative coloring.
Circuit design
This week I broke my circuit into several pieces for easier reuse.
Routing Charlieplexed LEDs is super fun...
Soldering and debugging
Because the endmill I used was a little blunt it left some copper traces which caused shorts on pins. It wasn't fun debugging.
Final product
The level works!
