Here is the diagram of my Arduino infrared close proximity sensor. As you can ... R-C components R2-C1 is vitally necessary to suppress potential power supply disturbances whereas R3 is an essential ...

This project involves creating a simple door status monitor using an Arduino Uno, an IR sensor, and an LED. The purpose of this project is to detect whether a door is open or closed and display the ...

This project outlines one transmit and one receive module for RS323-compliant serial communication via IR. To transmit serial data, an Arduino creats a 38kHz square wave (to match the receiver's ...

Build a Bidirectional Visitor Counter using Arduino and IR sensors to track entry and exit movements with real-time counting on an LCD display. This step-by-step guide covers circuit ... Later you got ...

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 ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...
