An Arduino Nano is the heart of the build, paired with a shield that lets it run a number of servo motors. The servos, one per key, are each assembled into a 3D-printed bracket with a cam-driven ...

The Arduino is perfect for this purpose, but choosing it ruined a perfectly good pun and we can never forgive that. Well, not exactly universal control, but similar functionality at any rate.

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on ...

The Nano ESP32 supports both Micropython and Arduino programming languages, providing a clear path for those already familiar with one platform to easily switch back and forth as needed.
