![]() ![]() Servo Motor Control - 50Hz Pulse Train Generator We just need to define the pin to which the servo is connect, define that pin as an output, and in the loop section generate pulses with the specific duration and frequency as we explained earlier. Now let’s take a look at the Arduino code for controlling the servo motor. ![]() It delivers a strong primary foundation in dealing with actuators and supports beginners jump into more fun with actuators.See Also Arduino Brushless Motor Control Tutorial | ESC | BLDC Servo Motor Control Arduino Code It focuses on controlling an actuator, SG-90 SG90 Servo Motor, using Arduino Uno and Arduino IDE. ![]() DIY Projects: The SG90 Servo Motor is popular among DIY enthusiasts for various projects, such as robotic arms and grippers, due to its small size and low cost.Industrial Automation: The SG90 Servo Motor can also be used in industrial automation systems for precise control over various functions, such as conveyor belt systems and material handling equipment.Model Making: The SG90 Servo Motor is frequently used in model-making projects, such as architectural models and train layouts, to control doors, bridges, and other moving parts.Animatronics: The SG90 Servo Motor is often used in animatronics projects, such as animatronic puppets and Halloween costumes, to control the movement of joints and appendages.RC Cars and Aircraft: The SG90 Servo Motor is used in remote-controlled vehicles, such as cars and aircraft, for precise control over steering, flaps, and other functions.Robotics: The SG-90 SG90 Servo Motor is commonly used in small-scale robots for controlling the movement of joints, arms, and other parts.This is repeated until the power is disconnected or servo is disconnected. The delay function will hold this position for 1ms. Then the servo is instructed again to go back to 0 degrees, as we had initialized before. Next, in void loop, we use the servo.write function again to tell the servo to turn to 180 degrees and the delay function will hold this position for 1ms. Then a delay function is used to create a delay of 2ms. At the beginning the default state of servo is considered as zero degree we keep this as origin position that is zero degrees. The servo.write function is used to tell the servo the degree to which it should turn. In void setup function, we use the servo.attach function to tell the Arduino board that the control pin of the servo motor is attached to pin 8 of Arduino (the function attaches the servo variable to the pin). Next, we declare a variable called “servo”. If you don’t already have this library in your Arduino IDE, then you can go to “tools” à “Manage Libraries…” and type “Servo” in the Library Manager and install the one from “Michael Margolis, Arduino”. Myservo.write(0) // sets the servo position to 0 degreesįirst, we need to include a library called “Servo.h” to be able to control various servo motors. Myservo.write(90) // sets the servo position to 90 degrees Myservo.attach(3) // attaches the servo on pin 3 to the servo object Servo myservo // create servo object to control a servo How To Add library Code //For more Projects: #include Overall, the combination of these components allows the hobby servo to be used in a wide variety of applications that require precise movements, such as robotics and remote control vehicles. The control circuit uses this feedback to control the movement of the servo motor. The potentiometer is used to provide feedback to the control circuit, allowing it to adjust the servo’s position accurately. The gearbox is an essential component of the servo as it allows for precise movements to be made by the servo. The DC motor is a high speed and low torque, but the gearbox is used to reduce the speed to around 60 RPM while simultaneously increasing the torque. How Servo Motors Work?Ī hobby servo typically consists of four main components: a DC motor, a gearbox, a potentiometer, and a control circuit. In addition, the SG90 Servo Motor is also commonly used in DIY projects like robotic arms, grippers, and various other mechanical devices that require precise control over their movement. These motors can be used to control the position of the steering wheel, flaps, and other parts that need precise positioning. The main application of SG90 Servo Motors is in small-scale hobby projects such as remote-controlled cars, robots, and aircraft. The SG90 is a 9g micro servo motor with a torque of 1.8 kg/cm and a rotation angle of approximately 180 degrees. It is a type of rotary actuator that provides precise control over the angular position of a device. SG90 Servo Motor is a small and economical type of servo motor that is commonly used in various robotic and automation projects. ![]()
