What's the coolest projects you'll done with a MCU?

Also, how do you personally control 7 segment displays? TTL/CMOS, an LED Driver (like MAX7219), charlieplexing, etc.

You can get a micro with enough IO, or use multiplexers

>charlieplexing
7seg displays have common anode or common cathode so charlieplexing doesn't work. Control multiple 7-segments like an LED matrix. 7 outputs from your MCU or a shift register to all separate inputs. Turn one on at a time very fast so it looks like a solid light.

Dual servo controller for brushed DC motors.

This version's gonna go in a robot that plays the pan flute.

made a UV lightbox from a protoboard and printed a custom board to replace it.

This micromouse robot. I learned a lot building it but I'm pretty sure I'm going to have to design a better version if I want it to actually be able to complete a maze properly.

This is beautiful. I think I've seen one of your threads. What is the processor used?
