In this Raspberry Pi Wiimote controllers guide, we will walk you through the process of setting up a Wiimote on your Raspberry Pi and show you how to setup both cwiid and wminput.
Utilizing Wiimote controllers on the Raspberry Pi can be painful to deal with due to its handling of the Bluetooth stack. While they run over standard Bluetooth, their actual functionality is not picked up as a conventional joystick device like Xbox controllers and PlayStation controllers.

Instead to support the full functionality of Wiimote controllers in a way that most applications can support we must utilize two pieces of software.

These being cwiid and wminput. One acts as a library that interprets the Wiimotes actions into joystick actions, the other being somewhat of a driver that creates an input device that applications can utilize easily.

Connecting ‘Xbox Controllers’ to the Raspberry Pi

If you have ever tried to use an Xbox controller with the Raspberry Pi, you will find very quickly that they do not work correctly right out of the box. In fact to get them working you will be required to install a special driver.

With the newer Xbox One controllers that feature the Bluetooth functionality, you will also find that they will need extra work on top of the driver installation to get them to run. Namely, they are not properly supported by some of the Bluetooth functionality that is switched on by default.

This guide will show you how to get your Xbox Controllers up and running on the Raspberry Pi, while also walking you through how to get the newer Bluetooth enabled controllers to pair successfully on the Pi.

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’.

Connecting the NXT2WiFi Webserver to a WLAN

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.
