Parts List Details
           You may or may not be familiar with the parts above so a picture of each item has been included to help give you an idea of what they look like. I'll go through and explain each part briefly below.

5v & 9v Power Supply
           The 5v power supply is used to power the PIC & logic inputs to the L298 while the 9v power supply is used to power the motor through the L298. The 9v is only fed to the motor while the 5v is fed to both the PIC and the L298.

ICD2-Tiny Pic Programmer
           This is a smaller version of the larger & much more expensive ICD2. ICD stands for In-Circuit Debugger. This means that the programmer not only programs, but also features debugging capabilities. It comes with a 15v programmer that will be necessary to power it.

9.2v Stepper Motor
           This is a standard 2-coil stepper motor with a 9.2v rating. It is also rated at 0.9° per step. This means it turns a full circle every 400 steps (something we can keep track of).

L298HN H-Bridge
           The L298HN chip is a rather odd looking chip with a non-standard pinout. It has 15 Pins in total although we won't be using them all. This chip is manufactured by ST and you can get free samples of it at their website.
