IoT-based farm security and monitoring system using Arduino, GSM, and IR sensors. This project implements a geofencing system for agriculture that detects intrusions (humans, animals, or unauthorized ...

A minimal example that reads a digital IR (obstacle/proximity) sensor on pin D2 and lights the onboard LED (pin 13) when an object is detected. The project is configured to build with PlatformIO for ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Hello Connections, followers, Electronics Engineers and DIY Hobbyists! Today we are going to explore simple Arduino projects built using sensors. Discover creative solutions such as obstacle detection ...

Today, I learn how to use IR-sensor and with the help of following component I made LED-IR sensor Arduino project. Component: IR-sensor Led Breadboard Arduino with cable Jumper Wires. Here is the code ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware and ...
