hi there all
for one of my projects I'm looking at using multiple high current RGB LED's, 3W LED's where each colour is 1w. I know Arduino cannot cope with that so i need something between the two - i looked at a Darlington array ULN2803A but that has a maximum of 500mA - i think i need 1A of more.
Any other idea's on how to amplify the PWM signal - or any other ways of doing it?
Many thanks Matt
