Digital Fanatics

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 components such as motors and sensors, can be used in combination with the Arduino platform.

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 plain C.

If you don’t feel like working with C, do not panic. We will start by exploring the IDE and examples provided from the Arduino project.

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 board is the ATmega644p chip, a bigger brother to the ATmega328 of the Arduino UNO board. The Sanguino board provides, 32 GPIO-pins, 8 analog pins and 6 PWM pins. On the memory side, 64kB of FLASH and 2kB EEPROM provides non-volatile storage, while 4kB of RAM provides space for your stack and variables.

The Sanguino can be bought or built. For the builders, instructions are provided for a soldered custom PCB, a strip-board style construction and even a breadboard version. For the tinkerers out there, a break out sheild is also available. This way, you get easy access to IOs via terminal blocks for attaching your wires.

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 pixels per video line, but due to memory restrictions, the actual resolution used is 35×14 pixels. In black-and-white.

As a nostalgic side note, it is worth noticing that such limited resolution and colourspace is enough to provide a challenging game play. All the instructions, including code and schematics are available here.

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 are easy to find. You are likely to find them in old printers, scanners and floppy drives, as well as in photo-copiers and other machines relying on controlling the size of a motion. Another great thing about them is their usefulness – you can build robots, web cam stands and much more.
