A couple of questions, no project, just fooling around on a breadboard:
I have found that Darlington transistors seem to perform well with little
base current, even 1uA can switch a quarter amp. Seems really low for
base current, even though I know that's what they do best.
Also, I'm having trouble keeping Darlington off, and I need 100 ohms
or less pull down to keep it off, yet my base resistor drive resister is much
higher. I am suspecting somehow I am coupling
with my florescent overhead lights... a head scratcher.
