Using the HC - 05 Bluetooth Module is quite straightforward. First, connect it to your power source. You can use a 5V supply like an Arduino because the module has a 3.3V regulator on the breakout board. Then, connect the necessary pins such as power, ground, TX, and RX to your device.
When you start using it, pay attention to the LED indicators. A fast flash means there's no connection, a slow flash indicates AT mode, and a double flash shows a successful connection. You can switch between host and slave modes using AT commands.
Make sure the input voltage doesn't go over 7V to avoid damaging the module. Also, note the temperature range it can work in, from - 4°F to 107°F.
For maintenance, keep the module clean and dry. Avoid exposing it to extreme conditions. If you're not using it for a long time, store it in a safe place. And remember, you can customize the Baud rate according to your needs, with options like 4800, 9600, and others.
