This Simple LED Voltmeter Circuit works like a small battery checker with LED lights., unlike a phone battery bar, this circuit uses LEDs to show the remaining battery level in many small electronic devices. More LEDs turn ON when the battery has more charge and each LED turns ON at a different voltage level. The […]

Simple Power Strip Surge Protector Circuit
Simple Power Strip Surge Protector Circuit is like hero for our plugs, they help protect our devices from big shock of electricity called power surge or spike. Also, this surge can come when storm happen or when other machine turn ON or OFF. Inside power strip a special part called MOV take this extra electricity […]
Simple Water Level Indicator Circuit using IC ULN2004
This Simple Water Level Indicator Circuit using IC ULN2004 work like small helpers for our water tank; as it uses one special chip named as ULN2004 to control many things together. This chip can work with big electricity but here it only control lights, the lights show how much water is inside the tank. So […]
Simple 220V Time Delay Switch Circuit with Triac
Think this circuit is like a smart switch for our home things which wait for some time before power comes. This Simple 220V Time Delay Switch Circuit with Triac work like power button but it does not gives power fast, but it waits for little time and then gives power to light, fan or motor. […]
Simple 2 LED Battery Status Indicator Circuit
This Simple 2 LED Battery Status Indicator Circuit work like gas meter but for battery, as it uses LED lights to tell how much power battery still have. One light mean battery is full another light mean half power and last light mean time to charge. Also, it use small parts like resistors, Zener diodes […]
Simple Flip Flop Circuit
Think about small switches, they only do “ON” or “OFF”, but this Simple Flip Flop Circuit is same like that but for electronics. It stay in two state like 0 or 1, this small switch is very important it can remember stuff, keep data and help control what happen next like timing and by coordinating […]
