Last week, Ladyada joined our Community, and several of Adafruit's wonderful Open Source Hardware products are available from Newark element14!  Several of the newly added products are ideal for Arduino projects.   I dig Adafruit's handy 8x8 LED matrix modules which come in Green, Yellow and Red.  Only two I/O pins are needed to hook these displays up to the Arduino via I2C (plus power and ground).  Their great tutorial makes it easy to get started: These displays can be ...
New Release - Arduino Debugger   The Arduino Debugger has taken another step forward. Previously the debugger provided trace/break/step and graphical visualizations. The latest release allows the update of  variables and registers while an Arduino is running. Variables can be updated while the Arduino is running normally (in debug) or during a debug break (pause) event.   Read more about Modifying Variables On A Running Arduino at visualmicro.com   For this example we show ...
Introduction Earlier, I saw the post about the BrewPi and I got excited.  I mean really excited.  After reading up on it, I decided that I wanted to give it a shot and build one.  However, there was at least one thing that I wanted to change.  I didn’t want to crack open the fridge and start messing with the circuits inside.  That’s when I came across a blog post describing how to hack a wireless power switch and control it with an arduino.  This sounded ...
Introduction While working on a netduino web server, I really liked the idea of doing some PHP-like preprocessing on the websites before they were returned for the client.  Basically, the netduino would make a fantastic low power web server, and if I wasn’t expecting much traffic – I was thinking something for my own personal use – then it wouldn’t have to scale to a large number of users.   So, I wanted to add a mini compiler to it so that I could interpret so ...
