Learn how to build an IoT crowd monitoring system using the Arduino UNO R4 WiFi and Arduino Cloud. This project uses IR sensors and servo motors to count and manage the crowd in real-time.

You can tinker with your UNO without worring too much about doing something wrong, worst case scenario you can replace the chip for a few dollars and start over again. In this project bot follow the ...

Project Overview 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 ...

An IR sensor is placed near the servo motor so that a person must first cross the sensor before approaching the barrier. This setup effectively demonstrates how the crowd-monitoring system functions, ...

NTE30116 Tinted Blue 5mm Infrared LED Emitter (940nm) SM0038 Photo Module for PCM Remote Control System (38kHz) The principle of this setup is somewhat simple and self-explanatory. In this circuit, ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...
