CHAPTER 3LED Projects

IN THIS CHAPTER WE ARE GOING TO start building some LED-based projects. We will keep the hardware fairly simple so that we can concentrate on the programming of the Arduino.

Programming microcontrollers can be a tricky business requiring an intimate knowledge of the inner workings of the device: fuses, registers, etc. This is due, in part, to the fact that modern microcontrollers are almost infinitely configurable. Arduino standardizes its hardware configuration, which, in return for a small loss of flexibility, makes the devices a great deal easier to program.
