Googlium

An excellent way to get started learning how to program PIC microcontrollers when you are just starting out. Like I said, it's the best $15 you will spend if you really want to learn how the guts of these things operate. Each topic is explained in both the C programming language and assembly.

PK2CMD Software

For those using Linux and have access to (or want to use) the discontinued PICKIT2 programmer, the following is a link to the PK2CMD software which allows you to program the devices via the command line. It wont support chips made since about 2009 or so, but unlike Intel CPUs, 8-bit microprocessor technology doesn't really advance at a breakneck pace and you can do just about anything with the devices made prior to that time. Microchip also continues to produce every MCU they ever released (as far as I know) so its not like they go out of style.

If you want to know why someone might want to use a PICKIT2 instead of the newer PICKIT3 check out this humorous video below:

It went viral enough that it received a humorous response from Microchip themselves:

Fritzing CAD software/schematic editor.

If you've never used a CAD program for electronics design before, Fritzing is about the easiest one to get started with and it's what I used it to create the schematics for this site. Of course you can also use it to layout a PCB and send the gerber/drill files away to have a board of your own produced.
