Universal programmable digital timer switch

Many electromechanical devices operation is dependent on timing concept. Different constituent parts are programmed to function timestamp. In many home and industrial applications, timer switches form one of the major components. It usually used for such devices. this work, a simple but robust general-purpose universal programmable digital (UPDT) proposed. The UPDT switch software-based with an interface that can be connected variety act as their operations. designed perform cyclic up 100 times maximum switching time hours. module presented in work capable being utility load shedding device, water pump control, automatic poultry feed dispenser, lawn watering system, among others.
