Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...

Do you like Lionel, Marx, MTH, K-Line, Menards, and other 3-rail O gauge trains? Do you like big trains but have a small budget? This is the channel for you! Novices are welcome here! I received my ...

The TCRT5000 sensor is an infrared reflective sensor. This library is written to use with a TCRT5000 breakout's analog output and handle a threshold in software. These breakouts have typical two ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...

Abstract: LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and ...

Scenery projects on a layout will usually require an abundance of tools to work with. Yet modelers will come across certain devices that, while not a Swiss Army Knife, can be used in multiple facets ...

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 ...

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.
