Build a Custom Arduino Clone (Part 3) – Add a Compass

Arduino custom board, accelerometer and compass

This post is the last part of this series of articles (part1, part2) showing how to build a project using a custom Arduino board. To the accelerometer I added a compass. It begins to look more like a forest than an electronic circuit. The compass uses the IC2 protocol to communicate with the Arduino micro-controller.… Continue reading Build a Custom Arduino Clone (Part 3) – Add a Compass

Build an Arduino Clone (Part 2) – 3 Axis Accelerometer

Triple axis accelerometer and custom Arduino board

I just received a adxl335 triple axis accelerometer breakout board from sparkfun.com. I decided to test it on my custom Arduino board. Make sure, while wiring the accelerometer, to respect the maximum voltage of the device. This specific accelerometer accept a maximum voltage of 3.3v. You can get 3.3v from the Atmega328 Avcc pin #20. You… Continue reading Build an Arduino Clone (Part 2) – 3 Axis Accelerometer

Build an Arduino Clone

A basic Arduino clone

There are many different kinds of Arduino boards out there. Most of the time you will find one that fulfill all your needs but, sometime, you may want to build your own Arduino based board. Why would someone build its own Arduino board? Well, I can see two reasons to do that. Reason #1: Size and space… Continue reading Build an Arduino Clone
