The five clear LEDs are actually two colours: a perfect time to whip out the LIGEMDIO project for some LED testing:

Phototransistor Connections

Note that the PT333-3C Phototransistor uses a familiar 5mm LED packaging, but the collector/emitter pins are the reverse of what you might intuit. The short leg and flat edge are actually the collector and is connected to the positive supply side.

About LEAP

LEAP is my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know or send a pull-request.

NOTE: For a while I included various scale modelling projects here too, but I've now split them off into a new repository: check out LittleModelArt if you are looking for these projects.
