kasamiko Member Jun 17, 2012 #1 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

magvi Member Jun 21, 2012 #2 you can do it using for loops; like this one, for(k=0;k<600;k++) { indicator = 1; delay(1000); indicator =0; delay(1000); }

Wond3rboy Member Jun 27, 2012 #3 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.
