This circuit is not the very latest in robotics, but it may be of interest to those of you involved in making little robots using popular and inexpensive components. The proposed idea is a ...

What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated pretty quickly. At ...

Patrick McCabe's latest creation is a delightfully ironic combination of high-tech and low-tech that is sure to please. And just what exactly is this inventive tour de force? Okay, if you've read the ...

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on a ...

This module is modeled after an Etch A Sketch and combines Arduino and Processing sketches. With the help of Processing, you can trace a line using two controllers (potentiometers). One of the knobs ...

Rob Cai has used and Arduino Uno development Board together with an old VGA display to create an awesome digital representation of the iconic Etch-a-Sketch mechanical drawing toy invented by André ...

There are many ways to do this, but on the Intel® Edison board, I found that the easiest way is using the /etc/init.d directory. If this is your first time using init.d for start-up scripts, you’re ...

This solar tracker system uses the Arduino UNO board, a servomotor, 2 LDRs and 2 resistors to rotate the solar panel towards the Sun or a source of light. Here https ...

Need to quickly toggle or read some logic signals without the hassle of writing a quick program? [Thor_x86], aka [Eric], built an Arduino sketch that does just that — and he threw in the ability to ...

Engineer Saeki Yoshiyasu created a system that allows him to connect to a server with his iPod touch and draw a design on the web browser using nothing but a Graphics LCD, an Arduino, and a WebSocket ...
