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 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 ...

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 ...

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, ...

He printed off a Raptor hand (from the wonderful folks at e-NABLE) and hooked it up with some RC servos to give him a nice robotic hand to control. The actual code being sent to the Arduino is ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk.

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 ...
