Servo Motor Controller Circuit Schematic The circuit is designed to give control signals to the Servo.IC1 is designed as an Astable multi vibrator which can give pulses for the operation of the Servo.

The servo motor can be moved to a desired angular position by sending PWM (pulse width modulated) signals on the signal (control) wire.Usually, a pulse of width varying from 1 millisecond to 2 ...

READ MORE: Get Attuned to Servo-Motor Driver Tuning There are two types of servoamp inputs. Single-ended inputs are shown in the schematic above.

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

The circuit was successfully tested using a 1-kHz sine wave for the input with an amplitude of 4.5 V, and it produced a 1-V amplitude sine-wave output using a 1-V reference for the set point.
