Appendix A. Parts
Finding parts for projects can be quite a challenge. In this appendix, you will find sources for the parts used in the book as well as extra useful information such as pinout diagrams for some components.
Suppliers
There are now many electronic component suppliers that cater to the maker and electronics hobbyist. Some of the most popular are listed in Table A-1.
You will find that most of the suppliers listed here sell the Arduino Uno R3 and Raspberry Pi 2 model B recommended in this book.
Adafruit’s Arduino experimenter kit (product ID 170) and Sparkfun Arduino Inventor’s kit (KIT-11227) are both a good way to get started with a basic selection of components and an Arduino. The MonkMakes Basic Components Pack has most of the resistors, capacitors, transistors, and LEDs used in this book.

Resistors and Capacitors
Resistors and capacitors are very inexpensive, but this often means that there is a minimum order quantity of 50 or 100 with some suppliers. It is often better to buy a mixed starter kit of components.

Semiconductors
Components with part numbers like “2N3904” are easy to look up, but when it comes to finding common components like LEDs, it can be hard to find and it’s usually best to look for an assorted kit of LEDs on eBay or Amazon.com or as part of a starter kit.
