<p>The task operates the switching mechanism of industrial masses for repeated operations with the help of a user-programmable good judgment management device. The venture uses three switches and an Arduino microcontroller 328 IC that operates the masses in three modes: set, auto and manual mode. In set mode, the load works in step with the desired time, and in auto mode, it operates in the default time. In manual mode, the consumer can manually switch the load. In this mode user can turn on the load with the help of push buttons. The popularity of the loads and mode are displayed on a liquid crystal display. This venture is useful in industries in which the loads are operated in repetitive orders and in time c program language period.</p>
