This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

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 ...

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 ...
