This project demonstrates how to control 4 servo motors using an *Arduino Uno board. The servos are connected to the Arduino board and will move in a sweeping motion (from 0° to 90° and back to 0°).

A simple interactive Arduino UNO project to control 4 servo motors (SG90) simultaneously. Each servo is connected to a digital pin and moves in sync from 0° to 180° and back in a smooth motion. 1 D3 ...

If you are thinking of building your very own desktop robot arm and were intrigued by the project published yesterday which took you through the process of creating a mini robotic arm using Arduino.

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this ...

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as any other servo tester, the difference is that it can be programmed to do ...
