servo motor control using 8051 micrcontroller

The control signals for the motor's rotation are generated by an 8051 microcontroller. For foundational concepts and information about a servo motor, refer to the article on Servo Motors. The source code utilized is based on the AT89S51 microcontroller. The code is written in C, employing a function named motor void timer(int msec).

The system utilizes an 8051 microcontroller, specifically the AT89S51 variant, to control the rotation of a servo motor. The microcontroller generates the necessary control signals that dictate the motor's position and speed. The servo motor operates based on pulse-width modulation (PWM), where the width of the pulse determines the angle of rotation.

The implementation involves configuring the microcontroller's timer to produce precise timing intervals. The function `motor void timer(int msec)` is crucial as it defines the duration of the pulse sent to the servo motor, allowing for accurate control over its movement. The microcontroller is programmed in C, which facilitates the manipulation of hardware registers to set up the timer and generate the PWM signals.

To ensure proper functionality, the circuit design should include the following components: the AT89S51 microcontroller, a power supply suitable for both the microcontroller and the servo motor, and the servo motor itself. Additionally, it is essential to include bypass capacitors near the power pins of the microcontroller to filter out noise and stabilize the power supply.

Connections between the microcontroller and the servo motor must be established, with the output pin of the microcontroller connected to the control input of the servo. The microcontroller's ground must also be connected to the servo's ground to ensure a common reference point for the signals.

This configuration allows for precise control of the servo motor's rotation, enabling applications in robotics, automation, and other fields where accurate positioning is required. The overall design emphasizes reliability and efficiency in controlling the motor through a well-structured software program.The control signals for the rotation of the motor are provided by 8051 microcontroller.For basic concepts and know-how of a servo motor, refer to the article Servo Motor.
