Nigel Leitzell / Mbed 2 deprecated SmartHomeMobileBoard

The Smart Home Mobileboard project demonstrates successful communication using the integrated RF module header on the FRDM-K64F board as well as the serial port for UART communication to the serial terminal. The Smart Home project ultimately is based on creating an automated home controlled either by the mobile board (i.e. wearable device) or the Smart Home Bluetooth App designed in MIT App Inventor 2. This project was completed for ECE533 class within the IUPUI Purdue School of Engineering.
