Growing up, I used to have a dream that robots took over the world. So, it’s only right that 25 years later, I contributed to that terrifying existence by building my first robot buddy with the ...

Last time, we learned about the anode and cathode of an LED, how to distinguish their orientation, and the role of a resistor in limiting current.This time, we will combine an Arduino, a breadboard, ...

I have a bit of a love/hate relationship with the Arduino. But if I had two serious gripes about the original offering it was the 8-bit CPU and the lack of proper debugging support. Now there’s plenty ...

At this point you’ve almost certainly seen one of these low-cost portable soldering irons, perhaps best exemplified by the TS100, a pocket-sized temperature controlled iron that can be had for as ...

Last time, we used a light sensor to measure the ambient brightness with an Arduino. When the light hitting the light sensor ...

Electrical power systems engineers need practical methods for predicting solar output power under varying environmental conditions of a single panel. By integrating an Arduino-based real-time data ...

This article will help you build a simple Arduino-based DCC system. Growing up in the 1980s I was living the dream. I had an HO layout on a 4 x 8 sheet of plywood in my parents' basement in Reading, ...
