RAINBOWDUINO EXTENSION SHIELD V0.9B Rainbowduino Extension Shield is a breakout board of Rainbowduinos 192 separate LED driving channels. The channels are divided into three 8*8 arrays: red, green and blue for easier controlling. This shield is designed to ease customized LED projects based on Rainbowduino. Direct plug in Rainbowduino FEATURES 60.33mm180.61mm(3 multiple of KEY SPECIFICATIONS Rainbowduinos size) 824 LED matrix Can drive 192 separate LEDs drive Ext LEDs No extra junctions needed USAGE Rainbowduino Extension Shield is the breakout board of Rainbowduino, It can easily control 192(824) LEDs. It can also solder LEDs out of board. LED is upwards, and its back is the place to solder the pins. PROGRAMMING The code for details is linked on the depot page, please look it up if needed. EXAMPLES Rainbowduino Extension Shield is used to bright the LEDs in different patterns. The code below is able to control G10 and R31 to shine gradually as an example. You can change the style simply by modifying the parameter value of dots color array. The first element can choose the matrix in different color the last two parameters are used to define which one need to shine in row & column value.
