Hi everyone. I've been studying an astable multivibrator circuit, and I built one.
I don't really understand how all the voltages and currents go around the circuit. However, I do understand that it oscillates, that the output of each transistor is an input to the other, and that higher R/C values slow down the circuit. Is it sufficient that I understand those latter things and see the circuit as a black box, or do I really need to understand how the whole circuit works? If the latter is true, how can I best learn it? I have read all the web references I can find and I can't seem to follow where the voltages and currents are going.
My intention is that one day I would like to design circuits that can count, perform boolean operations, and incorporate AVR microcontrollers.
