Servo Motor Control Circuit Using 555

This is where the above servo motor driver circuit comes into play and this circuit uses ic 555 to perform this job.

Servo motor control circuit using 555.

In this project we are making a servo motor controller using 555 timer ic. The 555 timer ic is very cheap as compared to a microcontroller and it does not require any programming. A dc motor 2. Servo motor control circuit.

A before buying or using a servo one must know what s inside it and how it works. B there are total 3 wires that come out of a servo motor. This gives more precise movements using this motor. We use the very popular 555 timer ic in astable multivibrator configuration to be able to generate the desired pulses.

But servos require special circuitry for it to operate. Each motor has its own unique properties and requires a particular circuit configuration to control it. Control three types of motors with 555 timers. Dc servo and stepper.

This circuit will show how to control a servo without using a microcontroller. But unlike generic dc motor we can control the angle of servo motor. 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. 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. Circuit description and working of servo motor tester circuit using 555 ic. Using the humble 555 timer chip you can control three different types of motors.

Typical image of servo motor and dc motor. To positive of supply 2. Servo motors are basically rotary actuators that enable precise control of angular position acceleration and velocity in various embedded system applications. 1 potentiometer either analogue or digital 3.
