Hi...tnx for share...I working in a joule thief charger that uses one big transistor, the Q is this transistor array chips like ULN2803A can be conected in series? It can be conected like a standart transistor using just 3 legs of the chip CBE or need special conection? can I make a darlinton pair with 2 2n3904?
Why are you using a 1ohm resistor? I'm kinda new with this so please excuse my stupidity
Also is there a reason for using that other chip instead of only the arduino? What does it do?

can you use any stepper motors in an arduino? Or only certain ones?

I mis-spoke in the video. The yellow wire puts out about 4.4Amps the red wire (5v) puts out around 1.2Amps. Sorry.
