Repeating Timer

[kasamiko]

Hi,

I want to built a timer that will be ON for 10 hours then OFF for 30 minutes using PIC like 16F628A..

Also it has a 3 minutes power ON delay in case of power interruption..

Hope somebody has a similar circuit or maybe a link for a similar project...


TIA

you can do it using for loops; like this one,
for(k=0;k<600;k++)
{
indicator = 1;
delay(1000);
indicator =0;
delay(1000);
}

Hi, sorry for the late reply. You can also try using an RTC with a alarm output. That way you can have accurate timing. I have used the DS12887 parallel RTC with a PIC(its old fashioned), you can get one in SPI or I2C.
