Servo Motor Control Circuit Using 555

The servo motor tester circuit using 555 ic passes pulses of varying width to the motor attached with the circuit and then monitors the output of the motor and evaluates the angle to which it turns in respect to the input fed to the motor.

Servo motor control circuit using 555.

To positive of supply 2. In this project we are making a servo motor controller using 555 timer ic. Each motor has its own unique properties and requires a particular circuit configuration to control it. The 555 timer ic is very cheap as compared to a microcontroller and it does not require any programming.

This is where the above servo motor driver circuit comes into play and this circuit uses ic 555 to perform this job. But unlike generic dc motor we can control the angle of servo motor. Dc servo and stepper. A servo motor is an actuator which is used to control the angular position velocity and acceleration.

To negative of supply 3. Commonly having a rotation limit of 90 o to 180 o servo motors are dc motors equipped with servo mechanism to sense and control angular position they are used where there is a need for accurate shaft movement or position. Typical image of servo motor and dc motor. Servo motors are basically rotary actuators that enable precise control of angular position acceleration and velocity in various embedded system applications.

But servos require special circuitry for it to operate. A servo motor is made up of three key components. We use the very popular 555 timer ic in astable multivibrator configuration to be able to generate the desired pulses. Control three types of motors with 555 timers.

A before buying or using a servo one must know what s inside it and how it works. Circuit description and working of servo motor tester circuit using 555 ic. A dc motor 2. Servo motor control circuit.

1 potentiometer either analogue or digital 3. Using the humble 555 timer chip you can control three different types of motors. This circuit will show how to control a servo without using a microcontroller. The circuit uses a 555 timer ic which is very cheap when compared to a microcontroller and also which doesn t require programming.
