As stated before, you will need to make sure you have all the tools. So, go ahead, hunt and gather away. Grab at least one of each of the following and more than one of each, if you, like us, are prone to accidents:
A laptop to download the Raspberry Pi image and set up everything
Raspberry Pi—Model B/B+ (preferred), a keyboard, and a mouse for the Raspberry Pi (optional)
SD card with 4GB memory (SD card preparation was explained earlier in this project)
USB Power Adapter (Rated 1.0 A) and Micro USB power cable
Ethernet cable
Wi-Fi adapter—(optional) refer to the eLinux wiki for Raspberry Pi for verified peripherals
Breadboard
Jumper wires
Discrete Resistor Values
A work bench (or a clean working surface—hopefully you have one)
Good thoughts and a can-do attitude
You will need all of the tools listed in the previous section to get through this project. Take your time and make sure you have everything handy!
