Up to about a minute, no problem. More than minutes I would not recommend it and would rather use dividers or something else.Thanks for the info, that pretty much answered my question. Its not for any particular project, just something I have been curious about but couldnt find any infor. The question popped up because I am working on something that needs a delay of one or two seconds. While I know this should be within the abilities of the 555 it got me wondering just how long of a delay I could get. And wondering about that got me wondering just how short of a delay is possible.
Sorry, that's classified.What is the widest range of frequencies anyone can get out of a circuit using just one 555 and no decade switching?
I can wire up a 555 without having to boot up any computer or learn any software or buy (or make) any programming interface. Instead of de-bugging code, I can simply tweak a trimmer pot.I know this is old, but i wanted to add that since i started playing with pics, i wouldn't even consider using a 555 as a timer anymore.
Yes...you can make a 555 with a time constant of DAYS...but the accuracy is going to suffer, because large capacitors are not that stable. On the high end, 555s start losing performance at 1-200k. (Though I've seen them pressed a bit harder)Anyone know the max and min semi-accurate frequency output of the 555? I guess the min frequency would be dependent on how much the cap you choose leaks, but what is the slowest you have been able to make it go?
