This project demonstrates a line-following robot built using an Arduino Uno, IR sensors, DC motors, and an ultrasonic sensor. The robot can detect and follow a black line on a white surface and avoid ...

This embedded systems project combines line tracking and obstacle avoidance into a single autonomous robotic car. Built using an Arduino UNO, IR sensors, ultrasonic distance sensor, servo motor, and ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...
