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 ...

1. Joints - The Foundation of Movement Joints are the moving links in a robotic arm. They let the arm bend, rotate, or change ...

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, ...

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 ...

As a preview of his latest book, Arduino Project Handbook: 25 Practical Projects to Get You Started, Mark Geddes takes us through the project to create a simple Arduino plant monitor. In this project ...

An Arduino is a popular open-source single-board microcontroller. Learn how to program one and let the possibilities take shape. By The Big Book Of Hacks Published Jan 10, 2013 3:00 AM EST Get the ...

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

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 ...

[Martin] sent in a great guide to a simple Arduino based theremin. It’s a very small build – just a single common IC and some passive components – and easy enough to build in an afternoon. The ...

While it’s great to look at professional maker projects that use motion tracking cameras or giant 3D prints that break the bank, it’s also nice to look at simple Arduino builds too. This project takes ...
