[Photo: Xoscillo] An oscilloscope is an instrument used by scientists and engineers to observe constantly varying electrical signal voltages. Oscilloscopes can be useful tools, but they can be ...

Capacitive sensing isn't limited to your smartphone. In fact, you can use contact with human skin (or any other conductive surface) to trigger almost any circuit. And the Touch Board from Bare ...

After you’ve taken the plunge and decided to learn how to etch your own circuit boards, you’ll quickly find even the simplest boards are still out of your grasp. This is due mostly to the two-layer ...

We think of the Arduino as a rapid prototyping tool but we never thought of it as an FTDI breakout board before. [Ihsan Kehribar] wrote a quick post to show how it’s done. You’ll find an FTDI chip on ...

If you’ve been reading this blog for a while, you’ve probably seen us refer to the Arduino microcontroller on a number of occasions. This little circuit board is at the heart of many DIY projects, ...

A typical Arduino microcontroller board is pretty small, about the size of a credit card. This makes it suitable for embedding into all sorts of electronic devices. But it's possible to go even ...

Arduino boards are small, inexpensive devices that let you build things with sensors (to control anything from a robot to a home automation system). The Raspberry Pi is a small, single board computer ...
