Electronics prototyping in the United States has evolved rapidly over the last two decades, largely due to readily available components that enable experimentation without soldering. Jumper wires are at the core of this shift, acting as the essential connectors for DIY circuits, educational robotics, and prototypes. They bridge the gap between a circuit diagram and…

An Arduino button (pushbutton) is a simple input device. When pressed, it completes a circuit and sends a signal to your Arduino, letting you interact with your project. Use it as a doorbell, light switch, or for many other DIY ideas. Learning to wire and code an Arduino button opens the door to many fun…

If you’re starting with electronics, robotics, or DIY tech projects, you’ve likely seen the Arduino vs Raspberry Pi debate. But which one should you use? While they might seem similar at first glance, Arduino and Raspberry Pi serve very different purposes. One is a microcontroller designed to control hardware directly, while the other is a…

This guide presents the key features of Arduino IDE 2.3.6. It offers practical tips on advanced tools, troubleshooting, and sourcing equipment for both experienced engineers and beginners. This guide will first examine the core features of version 2.3.6, then address advanced tasks such as post-build actions, and finally provide recommendations for sourcing equipment in New…

You are finally ready to begin your project, but you realize you’re missing one vital link: the Arduino socket cable. Maybe you’re building a smart thermostat for your place in Denver, or you’re automating the garage door at your home in Cali. Or, perhaps it’s a last-minute science fair project sitting on the kitchen table…

Author Note: I have been building with Arduino boards for close to eight years, starting with a $20 Uno kit and a lot of burnt fingers. Every project below has been built and tested by hand, not copied from a spec sheet. Arduino projects are the fastest way to turn a $20 board into something…
