Chapter 4. Bit Twiddling
In this chapter we’ll make a cylon-eye-type LED back-and-forth scanner. Everyone needs one. Scanning lights were the only thing, besides maybe menace, that gave the cylons their personality. Would KITT have been half as useful to David Hasselhoff without his scrolling red lights? I think not. And now you can build your very own.
But I won’t lie to you. We’re building cylon eyes in order to learn a fundamental concept in microcontroller-specific programming: how to flip individual bits on and off inside a hardware register. And while that may not sound sexy, you’ll be using the ideas from this chapter in every AVR or microcontroller project you ever make from here on out. Flipping bits is just that important ...
