    Need help to make a programmable timer...

    Hey Rich, Thanks again for the tips! Those about the displays are really useful because in fact it saves from doing a lot of wiring. And that of partitioning the project in sections, program them one by one and then put them together is definitely the way to go. I will see what I come up...

The one thing that will make me suffer at least when starting to program those tiny things (I think) are the timers... for most of the...

    Need help to make a programmable timer...

    Thanks for all the suggestions. I program a little of C so I think PIC-C is the way. Will I have to use interrupts or anything like that? I see that far too complex... And I've been Googling for hours and could not find any timer examples in PIC-C... And delayms(1000) at the end of the loop to...

    Need help to make a programmable timer...

    I can use a 555 for the timing, a 4510 for counting, and a 4511 for the display... that's perfect, the thing is that it doesn't "add" the preset minutes to the countdown... it just sets the counter to the preset minutes and starts over the countdown... It is possible to do this "adding" thing...

    Need help to make a programmable timer...

    Basically, I'm bothering because I want to make a programmable timer... Here is the figure: The timer must have three buttons: Two of them add a different, programmable number of minutes to the count on each press. The third one resets the counter to 0. As long as the count is not 0, the output...
