Thanks, I'll do that!

Actually, no, I haven't touched microcontrollers before. I'm just used
to +5V meaning that there is a signal, and ground meaning there is no
signal (from technical informatics courses, where you build simple stuff
from NANDs and NORs), so I kind of assumed that the reset would be
active high.

Thanks for the help, I'll try those things now - I hope this depleted my
repertiore of noob-questions for now :)
