Instead of upgrading, [fichl] came up with a device that turns his single channel amp into a completely programmable one, with just an Arduino and a handful of servos.

The Pico Serial Servo HAT, meanwhile, is a compact and efficient serial servo controller with two powering options, two serial servo connectors, and two programmable buttons for customization. Its ...

The proposed idea is a general-purpose tiny toy bot uses two Micro Servos work with an Arduino microcontroller. In this “differentially-steered robot” design, the Arduino is configured to control two ...

He also outlines the process of scaling up from the 4 servo demo to 12 servos on a standard Arduino. Sounds like it might be time to build your own version of a mouse-controlled Lynxmotion arm ...

Servo moves smoothed - this could be an interesting one if you work with robotics. And it is flagged by the Arduino team.

In other words, the attached servo will move to its default position (but perhaps not exactly).Since Arduino Uno/Nano allows you to access 1024 memory slots that will subsist while it is powered off, ...

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 ...
