Over the past few weeks I have been finishing up my senior project work here at Project54. The goal of this project is to have a wireless interface that is capable of controlling police cruiser devices from the outside of the car. Up to this point I have successfully implemented both Bluetooth and Wi-Fi connections between a handheld Motorola PDA and an Arduino micro-controller. Recently I have improved these connections and have been able to actually send commands to devices in the cruiser, ultimately allowing a user to wirelessly control these devices from his or her PDA. As of now the application allows for control of the light bar and siren on a demo car. The following photos and a video show the user implementing this connection for control of police cruiser lights and siren. Future work will be focused on making the interface hands free with voice recognition on the PDA.
