I hooked a speaker to the positive and negative rail on my breadboard and there is very substantial hum, kind of low pitched. Does this constitute an oscillation, and if so, how can I fix it?
I;ve got a 10µF cap on the input voltage, and a 1µF, and 0.1µF across the output of the 7805. I'm worried about damaging components so I don't want to mess around too much.
thanks for any input,
wes
