A few weeks ago we played with XBee wireless devices. Last week we played with accelerometers and compass. This week we will put it all together in a custom remote control. Our first project will be to remotely control a servo motor by using two Arduinos and two XBee modules. The remote control (transmitter) should be...
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...

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....
Light Emitting Diodes (LED) are everywhere. There is a good reason for that, we love them! Most of us are using LEDs to communicate information, debug our code or simply add some style to our electronic projects. One of the first things one normally want to do is pack a bunch of LED to...
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...
I just received two XBee wireless modems with an Arduino shield and an USB adapter board. I bought all these parts from Sparkfun.com. I followed the instructions from the Lady Ada website to configure both modems so they can talk to each other. Once I finished soldering the XBee shield stackable headers I tried...
I have been playing with my Netduino Plus for about two weeks now and I love it. So far, the most interesting thing about the Netduino is the use of the .Net Micro Framework (.Net MF). Being a C# developer for a decade now, I really enjoy being able to take advantage of this language in...
I just received my Netduino Plus. Netduino is an open source microcontroller development board working with the Microsoft .Net Micro Framework. The good news it that the pins layout of the Netduino is compatible with the pinout of the Arduino, which means you can re-use your Arduino shields. The Netduino Plus comes with a...
I made this short video to complete my previous post....
