I recently needed to measure how different materials affect light transmission for a gardening project.  I decided this was the perfect opportunity to try out the new logic level converter to run both a 5v LCD and a 3.3v light sensor on a single i2c bus.  I used the following parts in this project: Arduino […]

Update! See Step 32 to find out how to use this project with a green laser! Also – checkout the LaserTweet Instructable to make this project display data from Twitter: http://www.instructables.com/id/LaserTweet-Twitter-Projecting-Laser-Show/ This project uses an Arduino and some cheap audio speakers to create a real laser show with full X and Y axis control. The […]

The Geiger–Müller counter is a relatively simple tool to measure ionizing radiation. To increase sensitivity, construction presented here contains three (instead of one as usually) soviet STS-5 lamps. This is important for measurements of natural sources of (low) radiation like soil, rocks (an article about my trip with Geiger–Müller counter on Śnieżka mountain). Principle of […]

I had a Holux M-1000B Bluetooth GPS module that was just gathering dust in my room. I had bought it from DealExtreme back in the days when I had GPS-less (but external GPS capable) Nokia E51. Upgrading to a Nokia E52 has since made this receiver redundant. However, since getting an Arduino, and being put […]

I wanted to learn how to interface with I²C devices using my Arduino, so I bought a DS1307 clock and crystal kit from Earthshine Electronics. I’ve no association to them, but I’d recommend having a look at their shop. Their prices are very reasonable, unlike most Arduino component retailers. I²C is an addressable serial interface. […]

Lampduino is a computer-controlled free-standing floor lamp, comprised of an 8×8 RGB LED matrix. The lamp stands 45″ high and 18″ wide.  Light emanates from both sides.  It has various display modes, as well as an included editor for creating animations.  The lamp is controlled via an application running on a PC host.  The display […]

What is Pozyx? Pozyx is the first affordable and easy-to-use hardware solution that provides accurate indoor (and outdoor) positioning and motion information for Arduino. In order to achieve a positioning accuracy of a few centimeters, the pozyx system relies on a novel wireless radio technology called ultra-wideband (UWB). The accuracy achieved with this ultra-wideband technology […]

My second holiday project was a bit more fun than just blinking lights. I decided to tear apart a $10 RC jeep and control it with the Arduino. For this project, I added a motor shield on top of the Arduino that I purchased at the same Radio Shack where I found the RC car […]

A computer is a very handy thing to use in your robots. If you start listing all the features that can be used for robotic purposes you’ll find that it is cheaper to buy a netbook than buying LCD, wifi and bluetooth modules, cameras, speech synthesizer modules, keypads, memory card readers, speakers and many other stuff. […]

For the Smart Cities exhibition in Leeds in a couple of weeks, we’ve been building a physical representation of an agent based simulation. Hex Bug Spiders are relatively cheap hexapod robots that are controlled via an infra-red transmitter which has an A or B code so that you can control two simultaneously. The way it walks […]
