  • Just for the reference If I used 5v LEDs would it be possible then? Commented Dec 15, 2015 at 15:24
  • If you used 5V LEDs and the total current for all the LEDs on one colour channel was below around 20mA then yes it would be possible. Commented Dec 15, 2015 at 15:25
  • I'm still far from understanding the limits of arduino, but. I just checked the leds. They are just under 4mA/channel. Wouldn't that work with VIN pin powered arduino? Commented Dec 15, 2015 at 15:31
  • Then if they are 5V LEDs you can run around 5 channels in parallel without any extra hardware. Any more than that and you will need the MOSFETs regardless to handle the extra current. Commented Dec 15, 2015 at 15:33
  • It doesn't have to be MOSFETs, a bog-standard cheap NPN BC547 or similar would be fine. Commented Dec 15, 2015 at 15:55
