Hi there, Could anyone send me a circuit diagram for arduino running 18x 5V 3mm led's via darlington array +resistors and all connected to potentiometer to enable me to control brightness of led's? I've got a basic idea how to do it but don't want to blow up my arduino so if anyone could help me p…

not as fine grained as analogRead; 0-255

analogRead returns 10 bit values, 0..1023.
