Hey guys, new here to the arduino world! And my first project is a 116 RGB LED coffee table that I am currently working on! I got the table all built and framed, and all the LEDS in place, now it is just the tedious task of wiring these 116 leds! I did some research and found that the colorduino can only power 64 RGB LEDS, so I bought two colorduinos, and split my table into two 8x8 matrixs. I have yet to figure out how to connnect the two colorduinos together to work together. But that will be for later.
Anyways so far I have only done 2 rows of 8 leds, it has been allot of trial and error, I first used packing tape to isolate the connections and hold the pins/leds to the table, unfortunately the packing tape did not stick to well, and found that hot glue worked perfectly! Anyways since I am using heat and also such small wires (30 awg) I want to connect my row of leds to the colorduino to see if the leds light up.
So I guess my first question is, when the colorduino is first booted does it come preloaded with some sort of lighting sequence? Or will I have to program it first?
Second, My colorduino has two GREEN headers that say VIN and GND. as pictured below, Wich one do I use to power the colorduino, also the header says
VIN
VIN
GND
GND
Why is there two vins and two gnd? do I have to bring two wires to it? Also I beleive it said 5v is what I need to send to it?
