I need a prototype device created that plugs into a vehicles ODB-II port and detects when the vehicles ignition is turned on and off. When the ignition is turned on, I need the device to play an audible sound after 3 seconds of continuous power, indicating the device is active. When the vehicles ignition is turned off I need the device to play 3 audible words clearly. In addition, I need a green LED light on when the vehicles ignition is on and off with vehicles ignition is off; if possible.
