The document discusses setting up a 40-node computing cluster using Raspberry Pi single board computers to handle big data tasks. It describes connecting sensors like temperature and humidity sensors to Arduino boards, sending the sensor data to the Raspberry Pi nodes over serial USB connections, and coding in Arduino Scratch to read the sensor values. The goal is to collect Internet of Things sensor data on the cluster for big data analysis.
