Simple Tilt Sensor Switch Circuit
Simple Tilt Sensor Switch Circuit control ON/OFF of LED or buzzer, also this tilt sensor work like small seesaw switch. In this circuit , inside a sensor there can be a small metal ball. When sensor stand straight the ball touch two points and then the current can pass and when sensor tilts the ball […]
Simple Darkness Detector Circuit
LED turn ON by LDR when dark and LDR and resistor connect in voltage divider circuit. During bright light transistor base get low voltage so transistor stay OFF and during dark come LDR resistance goes down and base voltage goes up with transistor turn ON and LED light up. Hence, this Simple Darkness Detector Circuit […]
Motion Detector Circuit using IC 555
This easy Motion Detector Circuit uses IC 555 to find human from far, as circuit have two parts: Transmitter: IC 555 work like astable multivibrator and it make square wave signal and this signal goes out through IR sensor (infrared). Receiver: Phototransistor see IR beam and if someone moves and block the beam then phototransistor […]
AC Power Outlet with Timer Circuit
Unlike a standard wall outlet, this AC Power Outlet with Timer Circuit incorporates a built-in timer; as a result, it functions as a timer plug, also known as an outlet timer. Also, we can plug other device into it. Furthermore, a small chip called the 555 timer acts as the brain of the circuit, also […]
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 […]
