Arduino Internals

Summary

Knowing a little more about the hardware on your Arduino I/O Board enables you to better understand what it’s capable of doing by itself and where it needs some help. Now that you have a grasp of the hardware involved and how to read a basic electronic schematic, go ahead and get your own copy of the hardware documentation that matches your Arduino from the Arduino web site, www.arduino.cc. This is the starting point for any additional circuitry you may want to add to your invention. This is true whether you add a commercially available shield or design and build your own interface.

Now you move on from the Arduino hardware to the Arduino software. There’s a good chance that you may be spending some time using this software, so let’s ...
