i would like to control a bunch of 1 watt leds via Arduino.. The arduino output pins are 5v, and are only rated for 40ma or 50 ma, so i was thinking a transistor is my best solution here.. and that i have a bunch of 2n2222..
I have coded for rgb leds to cross-fade into each other using pwm. Works perfect with 5mm rgbs, but not sure if the transistor i have is capable of the load. Also not sure if grounds need to be tied together?
Ive only put a single series, simply to show what i want to do.
I wanna run these leds around the 300ma range, hence the 2 ohm resistor from battery
2n2222 specs
IC= 800ma
VCE= 30v
EDIT : FIXED PIC
Thanks for your time!
