Not all projects have to be massive, and some-times you just want a cheap, simple, small solution. The Adafruit Trinket checks all of those boxes, and despite its meager three I/O pins, it’s a great choice for driving just a few LEDs, or control-ling whole LED strips. It can be programmed via the Arduino IDE, is compatible with many basic Arduino libraries, and it’s small enough to fit into just about any project.
