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. ... to ~38kHz signal yielded by D9 of the ...

“Muxall open source Infrared Detector (IRD) for reflective sensing, light curtains, and fast proximity applications. Works with Arduino (5V) and Raspberry Pi (3.3V) TTL.” ...

This repository contains the code and instructions to build a Line Follower Robot (LFR) using 3 IR sensors, an L298D motor driver, and an Arduino Uno. The robot detects a black line on a white surface ...

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 ...

Connect the IR sensors to the analog pins A0 to A4 on the Arduino. Connect the motor driver to the Arduino and the motors. Power the Arduino and motor driver. Upload the Code: Upload the provided code ...

Nimbus started out as a simple, Arduino-powered robot, but the project has progressed nicely over time. The last revision simply avoided walls, using a Sharp IR proximity sensor to detect, then ...
