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.

Motion Detector with Arduino (PIR + LED + Buzzer) This project uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ...

Create a smart blind stick using Arduino to help visually impaired individuals navigate safely. This DIY project uses an ultrasonic sensor, buzzer, and LED indicators to detect obstacles and provide ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad.

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

By reading different values from the sensor, we can detect if is it light , dark or a value between them. Another element that we are going to use on this experiment is Piezo Buzzer. So what is it ?

Electronic systems can help the visually impaired. This project combines an Arduino Nano, a TCS34725 color sensor and a buzzer to assist color blind users.

Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.
