And we have just found out our teacher is retiring end of the school year, so i need to have everything flawless by then.

It's your homework assignment, how can you have no idea how to do it? Are all you classmates as clueless?

i am the only one in the class doing a PIC, so I have absolutely zero knowledge on the subject. My teacher just told me to go on pic axe. So cant you give me a helping hand? I mean its not going to hurt is it. At the moment im just doing stuff like this, but i cant seem to even change the values of the delay, or pins.

main:
label_30: high 0
wait 1
label_42: if pin0=1 then label_49
low 0
goto label_42

label_49: let pins = 160 'forward
goto label_30

Have you googled PICAxe & Delay?
the PAUSE xxx command would be pretty handy.

varkunus · 22nd June 2008, 04:59 PM

no i can do it on a flow chart, but i cant change the value of the pause its default 1000 m/s

blueroomelectronics · 22nd June 2008, 05:01 PM

The do multiple PAUSE 1000

A loop comes to mind.

varkunus · 22nd June 2008, 06:22 PM

right, so if i want do a day i gota do...

1000*60*60*24 = 86400000 right? And how do you do a loop function?

THe hardest bit for me to get my head around is when the client who this is aimed for calibrates it according to there working hours. So would it be possible for them to press a button at say 5pm when there work place closes, and then press another one when it open again, at say 7am. And then the PIC will always arm the alarm the alarm between these times? Or is that to complicated?

varkunus · 22nd June 2008, 06:40 PM

think i got how to make a clock. If it starts at 12pm this is what happens

main:
label_10: high 1 (high pulse sent out at 12pm)
pause 518400
low 1 (at 6pm a low pulse is send out)
pause 950400
high 1 (at 7 in morning a high pulse is sent out)
pause 432000
goto label_10 (back to 12pm)

That has nothing whatsoever to do with the problem at hand. The device could squirt hairspray, paint, lemon juice, or whatever and the problem would be the same. The point is that he needs help with the programming.

Besides that, Google must be broken where you are. Hint: it's near the top on the first page of results.

lol, I was wondering who would snap first. Not that you really snapped or anything, but this person does seem to be responding to post in some strange order without reading the whole thread, then repeating what has already been said or completely off base.

hehe. . .no, that's not me snapping. Me snapping is far less pleasant. Happily it happens very rarely, and (hopefully) never in response to a blatant troll.

He does bring to mind HiTech's signature, though.

Buy em books, send them to school and hope for the best. What else are ya gonna do?

P.S. That Google crack was a good one

varkunus · 12th July 2008, 08:34 AM

well i have done the programming my teacher confused me with wanting to include something else. But I didnt need it so now I have a PIC which will send out a high signal from pin 0 at night time 18.00-07.00 and at 18.00 each day it will send out a 1 minute LED pulse for the user to check its still accurate. Now I know that using a PIC will be much more accurate than using a 555 timer, but will it be the same accuracy as a timing circuit. And if not how much can I expect for it to loose each day
