Simple Flasher Circuit using LED and LDR
This simple flasher circuit uses an LED and an LDR to create the flashing effect; as the light level changes, the LDR changes its resistance, which controls the LEDs blinking. Hence, there is no need for big chips or transistors but still the LED blink happens, also it uses simple parts like resistor, capacitor and […]
Automatic Staircase Light Circuit
Automatic Staircase Light Circuit turn ON light when someone uses stairs and after some time it turn OFF by itself automatically; also it help keep home safe and saves electricity. Circuit Introduction: Regular stair lights: We turn the system ON and OFF manually using switches at the top and bottom; however, sometimes people forget to […]
