Hardware Options

Introduction

The virtual world example consists of 2 distinct parts

• The sensor part and its readout which is implemented on a micro-controller. The most common systems are Arduino or Raspberry Pi where the Raspberry Pi is the more powerful and more costly device (~ 70 US$ with case, power supply, SD card, bread board, cabling included) featuring a full blown Linux operating system. Programming can be done in Python with the interpreter running on the RPI.
  The Arduino is substantially cheaper (in the 10 US$ range) but also less powerful and without its own operating system. The code for this device must be cross compiled and is usually written in a C++ type language.
• The virtual world which is created in VPython

When using an Arduino the Arduino software development kit (SDK) as well as Python and VPython would be needed and communication with the PC would be done through a simple serial interface. In this case only the sensor readout is done on the micro-controller and the virtual world is implemented on the PC.
