Smart Servo Motor Control Circuit Using 555

The idea is simple use 2 switches to control the motion of the servo.

Servo motor control circuit using 555. Circuit diagram showing how to run a servo motor using ic 555. Servo motor control circuit. Servo motors are basically rotary actuators that enable precise control of angular position acceleration and velocity in various embedded system applications.

This shaft can be positioned to specific angular. A servo is a small device that has an output shaft. The 555 ic is configured in astable mode to generate the special signal for the servo motor to work.

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. This instructable provides a walk through of a basic servo driver using a 555 ic chip 5 resistors a transistor and 2 capacitors. Servo motor controller using 555 ic shagufta shahjahan 615 views 5 months ago in this project we are making a servo motor controller using 555 timer ic.

We use the very popular 555 timer ic in astable multivibrator configuration to be able to generate the desired pulses. This gives more precise movements using this motor. But unlike generic dc motor we can control the angle of servo motor.

The circuit uses a 555 timer ic which is very cheap when compared to a microcontroller and also which doesn t require programming. This is the simple basic design of servo motor controller with pulse generator. And connect signal or reference pin to the collector terminal of the transistor.

It uses the cmos ic 7555 in the astable mode to generate pulses to drive the servo motor. Make connections as shown in the above shown circuit diagram. Ic servo motor timer ic 555 servo motors are employed in variety of applications like robotics industries computers doors toys and much more.
