![]() ![]() The servo motor should move to 0 degrees, pause for one second, then move to 90 degrees, pause for one second, then move to 180 degrees, pause for one second, then start over. Once you’ve connected the parts according to the wiring diagram above, open up the Arduino IDE and upload this code to the board: #include This library is included with the Arduino IDE, so there’s no need to install it. We’re going to use the Arduino’s built-in Servo library to program the servo. Once you have all of the components, connect them to the Arduino following this wiring diagram: You’ll learn basic to advanced Arduino programming and circuit building techniques that will prepare you to build any project. If you want to learn more about the Arduino, check out our Ultimate Guide to the Arduino video course. Otherwise, the current drawn by the servo could damage your Arduino. These are the components you’ll need to setup the example projects discussed below:ĭepending on the servo you use (larger ones especially), you should use a separate DC power supply to power it. ![]() Now let’s see how to use an Arduino to control a servo motor. Connecting the Servo Motor to the Arduino For most servos, a 1 ms pulse results in a zero degree rotation, a 1.5 ms pulse results in a 90 degree rotation, and a 2 ms pulse results in a 180 degree rotation. ![]()
