Modern RC cars can be pretty darn fast. That’s fun and all, but it also makes it easy to crash them into things. This problem ...

Some MD0657C2-R LED dot matrix displays for not a lot needed a project. The displays are mounted in groups of four on small PCBs, driven by a MAX6952, which are then controlled by a Pi Pico.

CU Boulder researchers are working to understand Front Range firefly populations, which put on evening light shows for a ...

Circuit Setup: Wire the 3-color LED module to the Arduino Mega as described in the circuit setup section. Optionally, use resistors in series with each LED pin to limit current and protect the LEDs.
