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 ...

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 ...

When motion is detected, the LED strip gradually switches on, lighting each LED sequentially in a warm colour. As movement continues, the strip transitions through a series of warm hues—such as orange ...

In this tutorial we are going to interface RCWL-0516 Doppler Radar Sensor with Arduino Nano. The RCWL-0516 is a motion detection sensor. It can detect motion through doppler microwave technology ...

A piezo buzzer and a TCS34725 color sensor, mounted on a small breakout board, are connected to an Arduino Nano. This prototype system was developed as part of the course “ From Sensor to Report ” at ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

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.
