Hello, I'm trying to program the blink sequence of the pic 16f84 u controller.
The programmer appears to be working well but when I install the chip in the circuit board slot and turn it on, nothing happens. I'm curious to find out if I need a reset button or something like that to start the program. I get the idea that I don't becuase mclr is there. Any suggestions?=)

Make sure MCLR is tied to VCC
Make sure the crystal is well installed with the right capacitor values,
make sure there's power on the board :D deuh... sorry ;)
make sure the supply line is 'round 5Volts and noise free (0.1uF +10uF installed close to the pic)
Post your schematic
post your code
