Connect RGB LED board to Arduino?
Connect each of the 3 &quot;L&quot; wires to 3 separate digital IO pins of an arduino e.g. D8, D9, D10 via a resistor say 470 ohms but the value is not too critical. Connect VDD to the arduino +5v.
Use the arduino IDE write a sketch that configures pins 8 9 and 10 as outputs and then see what happens when you send these pins HIGH or LOW. Theres lots more you can do. Good luck.
