Thanks , I have found the correct ones with 4 pins.But which ones do I need to order, Anode or Cathode and what's the difference?
What would you recommend, 5mm or 10mm leds?And how did you set it up / what are the schematics?
A led string is a option, but how many light does it give?
you should not need a LED driver IC unless your going to cut the 5M strip into several (more than 2) shorter strips and control each strip independently. You could just use 3x suitable NPN transistors per strip connected to separate PWM pins on the arduino
