Are you a math aficionado in need of a new desk toy? Then do we have the project for you. With nothing more than an Arduino and a seven-segment LED module, [Cristiano Monteiro] has put together a ...

Although there are other ways to do this, [Rod] has decided to write up his method of using two Arduinos and the I2C protocol to expand an Arduino’s IO capacity. As seen in the picture above, you’ll ...

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

If you’ve always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your ...

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, ...

The big picture: If you don't know anything about electronics but have always wanted to learn and build your own IoT project, Arduino has the solution for you. The Plug and Make Kit is a comprehensive ...

Developers, makers and hobbyists that enjoy using the Arduino platform or Raspberry Pi mini PC to create projects, but continually find themselves having to wire up switches, encoders and LEDs to ...

With these mods, this circuit will last quite a long time, especially if you make things easier for the relay by turning off power to the motor before switching directions. It is simple and effective ...

Check out this Arduino-based electronic component tester. The device is intended to give a simple way to test transistors, resistors, capacitors, diodes and MOSFETs, and such like. The Arduino tester ...

We're always fans of a good Arduino project. While a few Wi-Fi solutions have existed to connect your Arduino to the internet wirelessly, the release of the new Arduino Wi-Fi shield makes those ...
