In this circuit, the infrared emitter IRED1 is modulated by connecting its anode (A) to ~38kHz signal yielded by D9 of the Arduino Uno (TP1) while its cathode (K) to a ~1kHz signal available at D8 of ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

This Arduino project implements a smart obstacle detection and response system using an ultrasonic sensor, LCD, IR remote, LEDs, and a photoresistor. It provides distance feedback, visual warnings, ...

This project involves the design and development of an obstacle detection and navigation robot. The robot is equipped with infrared (IR) sensors to detect obstacles and navigate through its ...

This project demonstrates a dual-input detection system using Arduino Mega 2560, an IR obstacle sensor, and a capacitive touch sensor. The system independently monitors both sensors to trigger ...
