For just a few Euros, a basic plotting robot can be constructed. Based on two servos, an Arduino and a pen, it is hard to build a more simple construction than this. From the video, you can see that cheap … Continue reading →

Tap to the beat of your favorite song on the switch, and the Arduino will learn and follow. As soon as the beats-per-minute has been calculated, a LED-array will start to animate to the beat. All this is implemented in … Continue reading →

Racing slot cars can be fun, but knowing who’s fastest when requires precision measurement equipment. Enter, an Arduino-based lap timer. The timer detects the cars using an infrared beam and records the lap time. For each track, the best lap … Continue reading →

Using a small Arduino and a couple of sensors, a segway-like, self-balancing robot can be constructed. The most interesting part of the project is not the construction, but the utilities developed in the project. Using the Arduino2Lego library, Lego NXT … Continue reading →

Getting started with the Arduino toolchain is not hard. This week, we will look at the development environment, some tips and tricks for Ubuntu users and, as the grand finale, we will look at working with the Arduino using only … Continue reading →

The Sanguino board is a Arduino-derivate offering a more powerful CPU, more pins and more FLASH. All this, while being compatible with existing Arduino software. It is not physically compatible, so shields will not fit. The core of the Sanguino … Continue reading →

The Arduino is a highly versitile platform, and as such, it also supports Pong. Using three resistors, the sync and light values needed by a TV can be generated. According to the author, Alistair Parker, the Arduino can generate 100-105 … Continue reading →

Steppers are fun, so are Arduino. Combining the two means double the fun. Here is a three minute video showing how it is done. The original blog post can be found here. A great thing about steppers is that they … Continue reading →
