Microcontroller Based Reversible Motor Speed Control System San, Myat Kaung Oo, Hlaing Thida This system is based on the microcontroller basedreversible motor speed control system. The suntracking system uses a reversible motor to rotate thedesire direction. A DC motor drives forward andbackward direction to track the light. The H-Bridgemotor control circuit switches the forward andbackward movements of the motor. The two LDRs(Light Dependent Resistors) are used as inputsensors. A microcontroller PIC16F877A determinesthe DC motor to rotate the forward or backwardmovement based on the Rule-Based system and PWM(Pulse Width Modulation). The PWM (Pulse WidthModulation) controls the speed sequence when motorrun only in the backward direction to reach thecertain position. The Rule-Based system used in thissystem to control the motor to rotate the forward andbackward direction via the input sensors. The controlsystem is implemented by microcontroller Assemblylanguage. 2010-12-16 http://hdl.handle.net/20.500.12678/0000004927 https://meral.edu.mm/records/4927
