Hi everybody.
I have registered hoping to find the answer to my doubts. But far from learning the meaning of life, I only need one simple (or not xD) thing.
I'm studying 555 timer, I know its equations and its two modes, astable and monostable, but the answer is. How can I deduct its equations? Where do they come from? I cannot find the answer. I'd thank you could lend me a hand xD
The equations I am talking about are:
Monostable
Th = 1,1 Ra*C
Astable
t1 = ln2 *(Ra + Rb)*C
t2 = ln2*(Rb)*C
