Hey peeps
From what I have learnt I have managed to make some pretty nifty little LED effects and pretty lights. I have also learnt about the 4017 decade counter and the 4060 binary counter; I would like to make some sort of clock, whether it be with 7 segment LED displays or some other method. I am sure I can work out how to wire up the IC's so they work correctly and display the time (tho not yet tried, heh) but my main query on this project is about precise timing.
I can use a 555 timer to provide the clock pulses but would this be precise enough ? It needs to be a proper 24 hour clock, so needs to be accurate, and for some reason I have a feeling that maybe a 555 timer does not provide the most accurate oscillator (oooh .. good techy word there .. heh, still learning the terms). Am I correct in thinking this, and if so, what do you guys suggest I use as a replacement ? Any other suggestions or help you can offer on this matter would be great also.
AND ... heh ...
Anyone know the correct way to have a 4060 BCD IC reset at 8 .. at the moment my 4060 is going all the way up to 15, I need it to go .. 0,1,2,3,4,5,6,7,8
Thanks in advance
