You certainly can! But 5% accuracy (pretty good for a 555 circuit) has an error up to three minutes per hour.hmm i thought you could make a binary clock with 555 timers =(
You can show a clock with a 5% accuracy, but I expect anyone else would be ashamed!would you happen to have a schematic? =)
Have you actually done a search? Here is the first page of Google's results.FatChina said:a binary clock with minutes and seconds only using a 555 timer with 12+ nodes
Perhaps this would be a good time to learn.FatChina said:im not a good googler
That circuit syncs up a 555 to the AC line, then divides it by 60 to give you a 1Hz clock. If the AC line fails, the 555 will continue to oscillate at close to 60Hz, so your time is not too far off when the power comes back on. Is that what you want, or do you just want a 555 running at 1Hz?FatChina said:alright i found what i wanted.. but i dont know the other half

IC6???
Try to get a multi-turn trim pot if you can. It will give you better settability.FatChina said:just the 555 running at 1hz
Well, he did sayblueroomelectronics said:Well it IS a binary clock, the OP never said how many digits.![]()
Not sure what the 12+ nodes is all about. Sounds like homework.a binary clock with minutes and seconds only using a 555 timer with 12+ nodes
