AC motor speed controller is used to control the speed of electric motors, that operate using alternating current (AC). These controllers are important in industrial and commercial settings, where the speed of the motor needs to be controlled depending on the demand. Arduino UNO is an amazing board that provides an effective platform to make AC motor speed controllers. In this article, we will discuss the steps involved in making an AC motor speed controller using Arduino UNO.

Explanation of AC Motor Speed Controller
The first thing you need is an AC motor. Choose a high-quality single-phase AC motor rated for the required voltage and horsepower. You need to pay attention to the RPM of your AC motor as well. Then You need all the components provided above in the components list section to make this speed controller using Arduino UNO.
The circuit design for a motor speed controller is pretty simple. You just need to connect the components as shown in the circuit layout provided above or you can download it from the link available in the components list section.
After having the circuit layout, you need to upload the code to the Arduino UNO board. Here is the code that you can use to control your motor speed using Arduino UNO:
Once the code has been uploaded, you can test your speed controller by connecting a motor to the circuit. By pressing the push buttons, you can vary the speed of the motor.
In conclusion, making a motor speed controller using Arduino UNO is a great way to control the rpm of your motor with ease. Arduino UNO is a versatile and affordable micro-controller board that can be used for numerous projects. With simple circuit design, programming, and testing, you can have your own speed controller up and running in no time.
