If you plan to venture into the class with real hardware and get your hands dirty, then I recommend picking up the necessary equipment from either Adafruit or SparkFun. I have wishlists on both sites that contain the parts you will need. Even if you don't buy from one of these two vendors, the wishlists will show you what you will need.

Note that a few substitutions were made, as their catalogs are not identical. For example, Adafruit carries 220 Ohm and 2.2k Ohm resistors, which work equally well for the 330 Ohm and 1k Ohm resistors shown in several of the lectures. Additionally, the robot chassis are different, but it is ultimately up to you as to how to build your robot body for that particular project.
If you live in India, it might be easiest to order from a distributor, like Fab.to.Lab. I've listed the required parts below. Note that they do not carry the PTH Neopixel (addressable LEDs), but the Neopixel strip should work. You would just need to add wires or a header to it in order to plug it into a breadboard.
