The figure presented above is a complete circuit diagram of a Servo Motor Circuit. In this type of circuit we used to calculate the speed and position of servo motor by using two ICs
(NE555) which produces pulse width signal to control these, One of two IC used produces continuously the type of wave (square) which is controlling the speed of servo motor, And the remaining IC is used to control the angle if the motor shaft by producing the pulses of different widths. The mode in in which this IC is working is mono-stable. Potentiometer is also used for the adjustment of the position of servo motor. This circuit is very helpful for the applications of servo motor.
