In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

Basic motion sensing setup using Arduino, PIR sensor, LEDs, and push button for interaction & Motion-triggered alarm system with Arduino, PIR sensor, piezo buzzer, and LED alert. // first pic This ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

This project uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer. This code ...
