This document provides instructions for using an Arduino Bluetooth Voice Control application to control an Arduino board with an HC-05 Bluetooth module connected. The steps are: 1. Download and install the "Arduino Bluetooth Voice Control" app from the Google Play store. 2. Turn on Bluetooth on your phone and pair it with the HC-05 module by selecting it from the list of available devices and entering 1234 as the PIN. 3. Open the app, select the paired HC-05 device, and use voice commands like "Turn on Red LED" to control outputs on the Arduino board.
