When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. This tutorial shows how to hack your 5 volt Arduino board to run on 3.3 volts. It is a simple procedure involving ...

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 ...

The chipKIT hardware is compatible with existing 3.3V Arduino shields and applications, and can be developed using a modified version of the Arduino IDE and existing Arduino resources, such as code ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

With the ability to get root access to some of these new powerful pieces of hardware we call cell phones, we’re a bit surprised we haven’t seen more interfacing with external hardware. Here’s an ...

If you're the sort of hardware geek that enjoys playing with the Raspberry Pi or building projects using Arduino, a new product is available for the Raspberry Pi that you might appreciate. The product ...
