Derek Stinson
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.

- Commit message:
- 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
