Bluetooth serial with my arduino pro mini

This is a demonstration of progress made on one of my arduino projects. I have moved to using an arduino pro mini, and now interfaced with a HC-05 chip to give it bluetooth capability. This was the first time I have used a breadboard or made a voltage divider. The voltage divider was needed to step down 5V to 3.3V the HC-05 chip needs. I also re-implemented the serial interface code just to learn it a bit better, as I hadn’t worked with the code for quite some time.
