![]() If you’re into robotics or hobby projects, the SG90 9g Servo motor ( datasheet) is a popular choice. Three types of Servo motors that are popular are the 9g Servo Motor, the MG996R Servo Motor, and the Continuous Rotation Servo Motor. Check the datasheet for your servo to determine its minimum and maximum positions. Most servo motors have a range of 0-180 degrees. That means they cannot rotate a full 360 degrees. This makes wiring and configuration super easy. You can connect a servo motor directly to the pins on the majority of controllers (Raspberry Pi and Arduino) without using an intermediary chip. Unlike DC motors, you won’t need any additional sensors to achieve degree-level precision and accuracy.Īnother advantage of using servo motors is that you don’t need a motor controller. (I recommend the L298N.) The biggest advantage of servo motors is that you can precisely control the angle of the servo. ![]() ![]() If you want to control the speed, direction, and position of a DC motor, you’ll need to use a motor controller and an encoder, respectively. a DC motor is that you can control the angle of a servo motor whereas with a DC motor you can only control whether the motor is on or off. A DC Motor is a type of motor that converts electrical energy into mechanical energy using a magnetic force. What is a servo motor? A servo motor is a type of DC motor that can rotate to a specified angle. Well, you’ve come to the right place! In this article, I will show you how to wire and program servo motors using Python and demystify the concept of the “duty cycle” to calculate the servo angle. Are you looking to interface Raspberry Pi with a servo motor? Are you confused about how servo motors work?
