Im doing a DIY proyect and i would like to keep it as simple as possible. I need to drive 32 (20mA) leds in a line. Not a matrix. I have read that the max power of the Arduino Mega is 200mA global, so im way over it as they will be all turned on at some point.
Is there an IC that could get 32 inputs from the arduino and output them without the limited power of the motherboard?
I'm a noob, and even with all i read about multiplexing it seems to be too much for me.
Thanks in advance
