Speed control for DC motor with pulse width modulation (PWM) method using infrared remote control based on ATmega16 microcontroller

The speed control of direct current (DC) motor for various applications is very important. In particular requirement, setting a speed DC motor as the driving equipment must be performed remotely. Under that condition, conducted a research on a DC motor speed control with pulse width modulation (PWM) method of the infrared remote control. PWM is method that may be used as a efficient DC motor speed control. Controller used TV remote control to send data to ATmega16 microcontroller through the IR receiver. This command controls the L293D driver IC to control the direction and speed of a DC motor. To calculate the speed of a DC motor, perforated disk attached to the motor shaft is used and placed between the photodiode as a sensor and the LED. The results of the research are the direction and speed of a DC motor can be set from the infrared remote control with PWM method using ATmega16 microcontroller. Furthermore, the results of these settings can be displayed on the LCD every 7 seconds.
