This, like most of the DUMMIES series is a well put together and presented book. It has some very good projects in but you should be aware that you will of course need to buy some extra shields (add on boards) and components otherwise you'll get no where beyond flashing the odd LED or two. At present I am awaiting the arrival of the GPS shield to construct the GPS datalogger project. None of the projects are overly complex involving mostly the linking up of boards via wires on a breadboard along with a few other fairly basic electronic components. Now , as a techky I tend to build on breadboard to test something and then reconstruct it in a stand alone form but, should you wish you can simply box up the entire project on the breadboard and bung it in a box. Overall a very good and interesting book guaranteed to trigger some great ideas of your own.
