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 ...

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 ...

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 ...

Writing articles for Hackaday, we see funny projects, and we see dangerous projects. It’s rare to find a project which combines the two. This one somehow manages to pull it off. [Outaspaceman] is ...

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 ...

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 ...

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 ...

This could be an interesting one if you work with robotics, flagged by the Arduino team – a look at how to smooth the operation of a servo, to avoid jerking between positions. It’s from the YouTuber ...

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 ...

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 ...
