Step 7 Solder the components to the circuit board and program

Now this is more my thing... SOLDERING!

1. Start out with the hardest component - the microcontroller, I like to solder two diagonally opposite pins first to make sure it is aligned, then continue with the rest. (see first photo)
2. Solder in the eight surface mount 74373 chips. Make sure you have them aligned correctly I.E. the indents should line up with the indents that are printed on the PCB. (see second photo)
3. Now you can solder in the resistors - all 30 of them (see third photo)
4. Next up are the four ULN2803 chips (see fourth photo)
5. Then you can solder in the 7805, capacitors and the 10k resistor (see fifth photo)
6. And Finally, you can connect up your programmer to the ICSP port and program the hex file onto the microcontroller.

I think you forgot to include the ICSP port as one of the materials you need. Can i ask what sort of ICSP port you used?

You are correct! Thanks for letting me know.

I use the pickit2 programmer which accepts a 6 pin header connection (although only five are required for programming which is why I only have five on the board)

How can i use only 5 pins when the cable has 6? What do i do?

The sixth pin is not used for programming so I normally leave it out (because it would not actually connect to anything on the board) All you need to do is line up the arrow on the circuit board with the arrow on the pickit2
