As a follow-on to a previous post about the "Man Cave Sign," we wanted to share with you the portion that used Bluetooth and Android Apps. This tutorial by Darryl Gardner will show you how you can use the two apps he wrote (on the Google Play Store) along with an HC-05 or HC-06 Bluetooth module and a chipKIT-based device to transmit and receive data to and from the Bluetooth Module and the PIC32 MCU device. He also provides some sample sketches to get you up and running!
