Schematics, Help Please Answered

Hello, I'm trying to create a simple timer that sets off a device after a set amount of time. I'm using a schematic from a basic electronics book that my grandfather had given me a few years ago. And it seems simple enough to the point where I can understand how it works. But I just can't seem to figure out how to actually put it down on a breadboard to even test it. So if you could possibly help me find out how to place this down on a breadboard to at least test, I thank you very very much. -The picture of the schematic should be below.


What I really need is the stupid-man's explanation of the 555 timer. So I could actually understand how each of the other components interact and use each other. Would any of you know of a good site that may provide this?

For this circuit, what happens is when you push S1, you trigger a flip-flop that both turns on the output (pin 3) and allows C1 (or C2) to start charging through R1. When the voltage on C1 reaches Vsup*(2/3), it resets the flip-flop, turning off the output and discharging the cap. A slightly different wiring will automatically retrigger the flip-flop when the cap voltage gets DOWN to Vsip*(1/3), resulting in an oscillator rather than a "one-shot" timer.

Thanks I'll definitely do that. No, I only have Basic and Digital (Advanced) electronics. My grandfather passed away from brain cancer before he could teach me more. But he taught me what he could before he died.

. Read a little further into the book (or maybe a little ahead of where you are). Mr. Mims is usually very good about explaining what's going on.
. Did your grandfather give you more than one book? If so, they may include Mr. Mims' book(let) on 555s.
. Enter "555" (minus the quotes) into the Search box at the top of the page or Googling 555 +tutorial turns up a lot of good info.

Thanks a bunch! It is indeed one of Forrest Mim's books. It came with a module like kit along with another advanced digital electronics book. I'll look up some more pictures as well as read more into the book as well.

Yes, finding out the "pin out" in other words, the location of the designated pin numbers, will help tremendously.

. Is that from one of Forrest Mims' books?
. Plug your 555 into the breadboard, fairly close to one end of the board. On most breadboards, it will be straddling a "valley" in the middle of the board. Start adding your jumpers: from the hole next to pin 1 of the 555, jumper to ground (-6V, in this case), from pin 5 to a capacitor located elsewhere on the board (that why I recommended putting the 555 near one end) with one side of the cap stuck in the ground rail, &c.
. The numbers next to some of the components (eg, 46 & 47 next to the SPST/NO/MC switch) may indicate some numbering system on a particular breadboard.
