hi, im trying make an intruder alarm using atmel 89c52.since im a complete novice in using microcontroller i donno how to interface the various components required. i need to interface a keypad(4 or more buttons),LCD ,a buzzer and 2 sensors.how do i do that?
i need someone to tel me which sensor can be used if it is to detect opening of a door or window and how to interface it with mic? does it need any other circuitry other than sensor and mic?
One more thing... im using C language or programming mic and using keil. i have written some code but donno how to get started with keil...please help??
