Keypad & LCD Display

While I was still trying to figure out what to do these 10 keypads, I received an LCD Display I ordered on eBay. It’s friday, I have no better idea than plug them both on an Arduino and  code something.   I started from the circuit of the Keypad article and moved the wires connected […]

Playing With The Beaglebone

Playing With The Beaglebone

I just received my Beaglebone and started experimenting with it. The Beaglebone is a low cost, single board Linux computer with tons of IOs to interface with the physical world. My objective is to make a Python Robot using the Beaglebone as the brain and my Makerbot to build the frame. I found an excellent series of […]

A Simple Arduino Task Scheduler (1)

A Simple Arduino Task Scheduler (1)

My motivation to write a task scheduler framework is to help me faster develop new Arduino projects. In most projects, we repeat the same tasks over and over before getting to play with the new stuff. You can jump into the code right now by downloading it from my github account at: https://github.com/pchretien/scheduler. ITask Interface […]

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

This post is the last part of this series of articles 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. That make […]

LED Matrix and Arduino

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 create […]
