That makes sense.

I'm not using the pins, I'm using the 5V output.

Atm i'm not using a driver. I have one, but I'm just using 4 transistors which is working. But I need to put some resistance on it otherwise the transistors burn out. That's why I mentioned the 1ohm resistor.

So, if I use a driver, and put 5V through it directly with no resistance, then it should all be fine? The driver chip won't burn out or anything?
