In order to use the PixyCAM with the LEGO Mindstorms EV3 or NXT kit, you will need an I2C Adapter Cable. You can order a cable through some PixyCAM distributors, including the Robotshop. The PixyCAM for LEGO Mindstorms comes with a special Pixy-to-Mindstorms Cable, and is preloaded with a version of the firmware that speaks with the LEGO protocol by default. If you have Pixy for LEGO, just to the PixyMon Settings section below.

I’m intending to use several Arduino Boards as a cheap means of controlling a number of RFID Readers which will be used to detect the position of Locomotive Engines on my LEGO Train Layout. That said I need a way of connecting these Arduinos to the Raspberry Pi which is the Master Controller for the layout.
The easiest way of Connecting an Arduino to a Raspberry PI is using USB, however the PI’s USB ports are need for WiFi Keyboard, Mouse, etc. So in many cases USB is out, especially if you are using a Raspberry Pi Model ‘A’.

The simplest way to connect to the NXT2WiFi Mini-Webserver Module is via an Ad-hoc Network, also called WiFi Direct network where devices communicate only peer to peer (P2P). There is no base and no one gives permission to talk. But this method is limited to the fact you can only have access through a single browser enabled device to the NXT2WiFi at a time. To get around this limitation access to the [NXT2WiFi] via you Wireless Router/Modem is the answer.
