Controlling the variac through arduino with remote access control using the stepper motor

Abstract

In this paper being presented, we propose designing the controlling system using an Arduino Uno microcontroller board for an auto-transformer attached to a permanent magnet stepper mechanism. We can create a control model by employing a stepper motor regulated with an Arduino Uno board. In the presented method of Arduino plug-in contrsol-based design, altering between states is attained by event triggering or provisional modification like a manual operator input which is maintaining the probable voltage output in autotransformer. The system involves the interconnection of drivers to the stepper motor connected to the autotransformer with the help of gear arrangement. The stepper motor was controlled through an Arduino Uno microcontroller board and as per the program requirements as per the application output through variac. The Arduino is fueled by a battery and a LED is linked for its indication.
