Design a car security system which has 4 sensors on all 4 doors. The system works such that it sounds an alarm if it detects any intrusion from any of the 4 doors. When the alarm begins -to sound, a timer (7 segment display) begins to count down (from 9 to 0). When the counter reaches 0, the systems sends an sms alert to the car owner.
-Also make the circuit on Proteus or Xilinx
This is a prototype circuit so sms alert can be indicated by lighting up an LED.
