I need to connect 200 LEDs to one output, and another 200 LEDs to another output, Each 200 LEDs needs 500mA and the arduino can support 20mA per output, how do I amplify the current without damaging the arduino board? I heard about transsitors but I didn't understand how to connect them... My pro…

How do I connect 200 LEDs to arduino?
