This document discusses controlling an LED light using Bluetooth from a Raspberry Pi. It includes the Python code to set up a Bluetooth server on the Raspberry Pi, listen for connections, and turn the LED on or off depending on the data received over Bluetooth. It also mentions using App Inventor to create an app with blocks to control the LED over Bluetooth.
