Change the angular values from (0, 90, 180) degrees to (1000, 1500, 2000) microseconds. In this sketch, we’ve replaced each write() function with a writeMicroseconds() function.

The sketch below demonstrates how to use the writeMicroseconds() function: #include If you want more precise control of your servo, you may want to use the writeMicroseconds() function instead of write(). However, there is a function that allows up to 1000 steps, called writeMicroseconds(). Using the write() function only allows for a maximum of 180 steps. Some servo motors have a range of 180 degrees, some have a range of 90 degrees, and some have anywhere in between. The write() function will work for most servos, but not all. We’re calling the function through the servo1 object, so we use servo1.write(angle), with 0 degrees, 90 degrees, and 180 degrees. The angle changes the pulse width sent to the servo motor, which then determines the amount of rotation. The angle is in degrees, from 0 degrees to 180 degrees. To move the servo, use the write() function with the angle of rotation as the argument. The attach() function takes one parameter – the pin that the servo is connected to. In the setup section, we initialize the servo with the attach() function. On the next line, we declare a pin variable called serverPin and set it equal to Arduino pin 9. On the next line, we create an object called servo1 to reference the specific servo motor throughout the code. On the first line we include the Servo library with #include. 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.
