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 electronics is where this project really shines, with an Arduino controlling the mode of fire (auto, semi-auto, and a 3-round burst), and the number of rounds per second adjustable with a pot.

This circuit is not the very latest in robotics, but it may be of interest to those of you involved in making little robots using popular and inexpensive components. The proposed idea is a ...

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

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 ...
