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 ...

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.
