Abstract
A home security system includes a plurality of alarm elements; a central console including a microprocessor in wireless communication with the alarm elements and effective to receive a signal from the alarm elements; an automobile including an alarm system in wireless communication with the central console's microprocessor and effective to activate certain alarm elements when the automobile's alarm system is in close proximity to the home security system and when the automobile is started; the microprocessor being connected to a tri-state analog to digital convertor which includes a plurality of resistors whose resistance values cooperatively determined an accuracy of analog to digital conversion with respect to the received signal transmitted from the alarm elements. An EEPROM that includes gray scale conversion is also realized.
