Okay, so recently got into breadboards and learning about electrical engineering and computers. And by recently I mean 3 days ago.
I have an ne555p chip. I am trying to make an astable clock signa for my projects.
lI have no way of showing a diagram.
R1-2k R2-100k c1 10uf c2 10uf(across + -pins) c3 -0.3uf But I basically followed every YouTube video I can find and it is set up EXACTLY like ben eaters tutorials except I have a 10mf electrolytic instead of a 1mf electrolytic capacitor
I've also tried every combination of R2 and r1 with every possible resistor from 220ohm to 1d ohms and the timing really does not change just flickers very fast??
. So I set it up like that and the light flickers but not at a stable rate. If I put the 2nd 10mf capacitor across the positive and ground pins and it suddenly started pulsing at at bout 2 times a second which seems more accurate. I can also take away that extra capacitor and it stays in a stable pulse. But when I plug anything else into the board interferes with the output signal. E.g. I have a monostable 555 hooked right next to it and when I press my button for the mono stable 555 the astable starts blinking faster. And if I plug in a 74hc393 4bit counter (or any other chip I have ) the astable pulse turns into a flicker but does not count on the clock. Please I'm very new to this and I've been reading and reading all weekend now I've gotten no where if anyone can point me in the right direction or just give me an idea of what's going on. I'll try to post a pic of my set up.
