thanks for the schematic, after a real quick look through ( I am currently doing my sons school stuff and took a second to check my thread) I think I understand some of whats going on,, I think I can definitely build this, I like the explanation but its gonna take a lot questions for me to truly understand whats really happening even though I can build it.. make any sense to you?? I can read a schematic well enough to be dangerous and can build circuits that work from them even though I don't understand whats going on.. anyway,, Im not sure why I burnt so many 555's out trying to drive a relay then,, I got the relays from an old tv set and don't have any data on them, after just looking at them they are spst, NO, 12v 20a relays... even thought I had a 12v PSU the voltage to the 555 was stepped down to 5v in a multivibrator config and I was trying to use it to trigger the relay to switch the output back up to 12v.. I ended up building a transistor scr tha completelty replace the 555 circuit altogether.. That was my first project in electronics and is what sparked my interest into building circuits and started the learning journey im now on..lolA 555 can drive most relays directly.
Here are some bits and pieces that might do what you want. Now I know what was left out--IC ID. Start with 555-OSC, A; 555-OS, one shot, B; 555-FF, flip-flop, C; 555-INV-R, D; up E; F; 4017- G; OR-H; INV-I.
No telling at what state everything will be in at power-up, but cycling thru once should make avery thing normal?
First SW push puts out a .1 to 1 s + pulse to cover up any SW bounce. resets C which is already reset,& advances 4017- G, one count. THe first stage of G, 0, pin-3 is high at reset so " 1' is used as first active step. When G-2, goes hi D-3 goes lo turning on R LED. Secsnd push turns on G LED, 3rd B LED. 4th push puts a hi on I input, output lo sets FF C. C-3 goes hi , enabling OSC, A. G continuously recycles, resetting every time G-1 goes hi. If SW is pushed again, FF, C is reset, stopping the clock - at a random output. May want to add an OR to G reset and diffrentiate C out for a secondary reset pulse. Wanted to keep first cut simple. Would prob. use a NOR IC for the OR & INV.
A review might be helpfull??
