Servo Motor Control Circuit Using 555

The circuit uses a 555 timer ic which is very cheap when compared to a microcontroller and also which doesn t require programming.

Servo motor control circuit using 555. We use the very popular 555 timer ic in astable multivibrator configuration to be able to generate the desired pulses. 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. 1 potentiometer either analogue or digital 3. This is where the above servo motor driver circuit comes into play and this circuit uses ic 555 to perform this job.

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. To positive of supply 2. B there are total 3 wires that come out of a servo motor. Circuit description and working of servo motor tester circuit using 555 ic.

Servo motors are basically rotary actuators that enable precise control of angular position acceleration and velocity in various embedded system applications. Typical image of servo motor and dc motor. Servo motor operates at the pwm principles which implies its angle of rotation is constrained by the span of the pulse applied to its control pin. Servo motor control circuit.

In this project we are making a servo motor controller using 555 timer ic. But servos require special circuitry for it to operate. Dc servo and stepper. But unlike generic dc motor we can control the angle of servo motor.

A dc motor 2. A servo motor is an actuator which is used to control the angular position velocity and acceleration. This gives more precise movements using this motor. The 555 timer ic is very cheap as compared to a microcontroller and it does not require any programming.

Each motor has its own unique properties and requires a particular circuit configuration to control it. Using the humble 555 timer chip you can control three different types of motors. A before buying or using a servo one must know what s inside it and how it works. To negative of supply 3.
