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 ...

This means that the servos stops and start very suddenly, moving as fast as they can between positions. In this video I'm going to show you two lines of very simple code to make things smoother.

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 ...

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 a ...
