Step 6Testing.

Testing.
If you did everything the same as I, it should work (see video).

If it doesn't work, make sure that you wired everything correctly and that the code is copied correctly. Also, be certain that your resonator (or crystal) is 20 MHZ. If you wrote your own code make sure there are no pauses in the routine that checks for low-high transitions.
