wiring with 7 led light disc
cosmicboy 2011-04-09 14:10:43 3162 Views2 Replies Hi, I bought the Light Disc with 7 SMD RGB LEDs.
The product page says that the labelling on the disc was wrong, and that the power pin in fact should connect to ground. When I tried this nothing happens.
As it turns out, what works is to connect the power pin (5V) with a pwm pin of the arduino and any of the 'R', 'G' or 'B' pins with ground. however, this is somewhat strange, and I have no clue how to sketch that...
Does anybody have a correct wiring image and maybe a sample arduino sketch for me?
Thanks

2012-09-14 22:43:22 I am really confused too...because DFROBOT sent me a light disc not soldered I solder my jumper pins on light disc has gnd on it yet it says version 2 has to be soldered and the 5v pin is actually switched to 12.....yet i do this and upload the skecth it does nothing i switch the 12 pin to gnd and it works both skecth ver1 and 2 works if you connect the gnd jumper on light disc to gnd on uno.....thanks for making something seemingly hard and confusing dfrobot when it isn't...you guys should make sure of your schematics and your sketch files....errr and delay is a bit to fast on 80.......gah ...i dont know if you sent me a ver1 UN-soldered or what but it works on GND on uno hooked up to lights disc...just ranting at you cause you made something so easy very stupid...thanks for nothing and I still havent gotten my lcd I ordered with my mega to work... newbreedwarrior

As the light disc has wrongly labeled. Please check the version you have, if you have a light disc with cables, then you had V1 version. If without cable, you have v2 version. Please check the code sample at

The connection is described in the code.
