This project demonstrates how to use an IR infrared sensor module with an Arduino Uno to detect the presence of objects. The IR sensor emits infrared radiation and detects reflected radiation from ...

the indicator led lights up when collision is detected. A continuous output signal is on the OUT port. The module detects the distance 2cm ~ 30cm, detection angle 35 °. The detection distance is ...

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 ...

V-LED This is the VCC pin of the LED. Connect this pin to the 5V pin of the Arduino with a 150Ω Current Limiting Resistor. LED-GND This is the Ground Pin of the LED. Connect this pin to the Ground pin ...
