Hello all
I am working with a Pic 16f628A, and can program it ( albeit I am primitive). I have a problem now where I am using the development board and writing a simple "Blink" program to flash an LED on Port RB0 and it works perfectly, until I breadboard it. When I put it on a breadboard, the LED will flash for about 15 to 20 seconds and then stop. When I turn the power off to the breadboard, the LED resumes flashing for about three seconds as the unit powers down, and then ceases. Then I can power up the breadboard again, and the LED flashes again for 15 to 20 seconds before stopping. Anyone have any thoughts on why the LED stops? The only hardware in my circuit is the PIC, an LED, and a 470 ohm resistor.
