Derek Stinson / Mbed 2 deprecated Motions_Secure_Server_IUPUI

Uses Arduino to take signals from a Lidar Lite v3 to scan a room. Arduino picks up a change in distance. Sends a signal to the k64. That k64 sets off sounds connected to a speaker. Those sounds are prerecorded on a flash drive. The k64 also flashes and LED that will flash until a turn off signal UDP packet is sent to it. It also sends an alarm UDP packet to another K64 that has flashing LEDs.

Dependencies:   EthernetInterface LidarLitev2 SDFileSystem Servo mbed-rtos mbed wave_player

Need to use this program also.

Revision:
0:a76470827116
Version .01 Alpha had to use an Arduino to read the Lidar sensor.  Any sensor will work as long as you pass a signal to the K64.  It will play sounds that you have on your flash card.  I used wav files I made from various sources involving security
