//Draw event
/*
This event occurs whenever the screen is refreshed.
It checks everything on the board using an x and a y through two repeat loops and draws it.
It is an important step, because all board values are changed to the normal versions:
5 -> 2 (conductor changed to head)
4 -> 3 (head changed to tail)
