Programmer: An ingenious device that converts caffeine into code.


Breadboards are still the go-to gadgets for prototyping, but many newer parts are only being offered in surface-mount packages. Is the day of through-hole PCBs done or nearly done, or can you still make everything you need without resorting to using a modified toaster or heat gun?  

And speaking of PCBs , ExpressPCB has stepped up again! So be sure to show your appreciation by checking out their great service. 
That's it, Enjoy!

Now that we're done with C pointers (whew!), we will study a C topic related to pointers: arrays. As a reward for our patience with the theory, we'll build another project using the chaser lights kit: a POV (Persistence Of Vision) wand.
