I have received my Arduino UNO Sparkfun Inv kit a couple of days ago :-D yay.
I am new to electronics so try to be nice ;)
I am making a LED light (probably 10-20 LEDs) that is connected to a motion detector to go in my hallway.I have everything running nice and smooth. The code is done and everything is running just the way I want on my bread board. But its only running 2 LEDs at the moment. The LEDs I will use are red 3volt 120ma diodes and I have read that the transistor (P2N2222A) can take 600ma, but I am not sure if I am understanding things right?
I have been reading about transistors for 30-40 min now and I didn't get much smarter. The data sheets are so hard to read if you don't know all the stuff in them :-( All transistors I can find seams to work with really high voltages or with very low amps.
Could someone plz explain some basics and help me to understand what I need to get something that will do the job?
