This Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.

The Core 2 sensor attaches to a heart rate monitor to keep tabs on your body temperature during workouts, the better to understand how the heat is affecting you. I found it a little fussy to set ...

The IR sensor array, which on the palm-sized vehicle consisted of just a handful of components, evolved into a PCB-backed bar nearly 0.5 meters wide. Potentiometer tuning was a fiddly affair, but ...

An automatic room light controller with people counter. Using arduino, counts the number of people in the room, with the help of IR sensor, turns an AC - DC LED bulb ON only when at least when one ...

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

DC motor could be controlled different ways with different approaches. One of the problems has been identifying internal specifications of DC motor such as Torque constant, back-emf constant, viscous ...

Infrared (IR) detector manufacturer SemiConductor Devices (SCD) has seen a significant increase in European demand for its products in the wake of the Russia-Ukraine war, the company has told ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

This project focuses on creating an automatic hand sanitizer dispenser using IoT, Arduino, an IR sensor, and a servo motor. The system is designed to provide a contactless and efficient solution for ...
