The project aims in designing a system which makes 230V AC motor speed and firing angle control through IR TV remote by using thyristor power. The controlling device of the whole system is an Arduino Nano Microcontroller.TSOP1768 receiver module, IR sensor, LCD display, zero crossing detector, AC motor with Triac is interfaced to the Arduino Nano Microcontroller. The data received by the TSOP1768 module from IR tv remote is fed as input to the controller. the controller converts this analog data into serial and fed as same to the microcontroller. The controller acts accordingly on the AC motor. A Triac and optically isolated Diac based circuit control the speed and firing angle of the AC motor 120watt. The IR sensor is used to detect the RPM of AC motor. Also, the speed of the AC motor can be display on LCD display. This system employs a zero-crossing detector for smooth operation of speed control. The optical isolation system safeguards the microcontroller-based system from high voltages. In achieving the task, the controller is loaded with a program written using Embedded ‘C’ language.
