How do I configure the hc-05 Bluetooth module?

If you have the HC-05 bluetooth module you can configure its basic parameters such as the default baud rate, device name, paring PIN and STATE pin behavior. Here is how you can configure the module. First, get yourselves a USB to UART converter. There are a multitude of these on the market with the FTDI’s FT232 being the most popular.

How do I connect my hc-05 to my Arduino?

That turned into this. HC-05 modules connect serial and Bluetooth devices using the Bluetooth Serial Port Profile (SPP). Many in the Arduino community have described how to configure and use these modules, including several Instructables. Using an HC-05 often requires an initial hardwired serial connection.
