When we’re done with this chapter, you’ll have either a working Cestino or a pile of malfunctioning ICs and a bone to pick with me. We’ll run a couple sketches on it for fun, to make sure it’s working, and that we can program it, and to demonstrate that yes, it does function in a mostly Arduino fashion before we go our own direction.
