Introduction: Controlling a Servo Motor Using Keypad

By
The basic operations of servo motor control have been discussed in interfacing servo with 8051. This project allows the servo motor to move to an angle specified by the user. The pulse train required to rotate the servo is produced by AT89C51 microcontroller. The desired angle of rotation is provided through a 4x3 keypad interfaced to the microcontroller. A 16x2 LCD is also connected with the microcontroller to display the angle of rotation entered by the user
