Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

Arduino sketch for controlling a Ferris wheel animation motor on a model railroad. Connects to JMRI for operation via a computer-based control panel as well as an auxiliary switch and proximity sensor ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

There are many ways to use an Arduino on a model railroad. These tiny, inexpensive, programmable computers can perform functions such as controlling signals, routing turnouts, and running animations.

Today, we are building a simple Arduino-based project: a light-following robot. This project is perfect for beginners, and we'll use LDR sensor modules to detect light and an MX1508 motor driver ...

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 ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

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 ...
