I want to make a Mechanical Wall Clock and I need the second & minute plus from PIC (12F675 or 16F84) Microcontroller so then I can operate the Mechanical Time Clock. Can you write code for me?
There are some RTC (Real Time Clock) that generate 1Hz signal in one pin only with connect them to 3.3V or 5V power suply. For example PCF8583 from philips.
Why do you need the minute pulse?
Normally, you would need just the seconds pulses, the mechanical clock should take care of the rest.
I could write some simple code to generate 1 second pulses.
OK, then.
If you tell me the duration of the seconds and minute pulses, I can give you some code. I mean the seconds pulse should probably last about 0.3~05seconds.
What about the minutes pulse? I suppose this will drive a relay or stepper motor.
