Fixed some bugs in v1.2.3 for Arduino Mega & Leonardo. Thanks to wiltwong and Markus Lange for testing! Download here: https://github.com/lincomatic/Colorduino/downloads
Thanks to wiltwong and Markus Lange, I have added support for Arduino Mega and Leonardo to the Colorduino Library. Markus also helped to clean up the code a bit for Arduino 1.x. I have added the ColorFill() function to the ColorduinoObject class, as well, so you don’t have to copy it from ColorduinoPlasma.pde. You can [...]
This past weekend, I finally finished building my 8×8 RGB matrix floor lamp. I call it Lampduino. A Processing sketch running on a host computer controls Lampduino via a USB connection. When turned on without a computer, it automatically displays a soothing plasma simulation. If you want to build one of your own, I wrote a [...]
The first step in wiring up the matrix is deciding on the method. I immediately ruled out soldering, because it’s messy, slow, and smelly. Also, it incurs the risk of overheating the LED’s as well as being hard to repair. I also ruled out using crimp-on connectors due to expense. After pondering it for a [...]
I’ve been pondering how to use my USBtinyISP to program my Colorduino ever since I got it. The problem with the beta board is that the ICSP header is positioned so close to the adjacent connectors that it’s impossible to plug a cable into it. I tried using header extensions to raise it up, but [...]
There were some bugs in the coordinate system of V1.0. I’ve fixed them, as well as rearranging the screen buffer for speed. You can download V1.1 from Colorduino Library for Arduino.
I wrote a Colorduino library for Arduino. It handles initialization and double-buffered drawing on ITead Studio’s Colorduino. It is also compatible with Itead’s Arduino RGB Matrix driver shield. Included with the library is a sample sketch to show how to use it, ColorduinoPlasma, which draws a pretty plasma on an 8×8 RGB matrix. To install [...]
ITead Studio kindly sent me a Colorduino for beta testing. The Colorduino was inspired by SeeedStudio’s Rainbowduino LED Driver Platform. Its form factor is very similar to that of the Rainbowduino, and the layout of the connectors was intentionally designed to mimic the latter. Both boards are based on the ATmega368 MCU, and are Arduino [...]
