The basic control functions for this system include monitoring inputs (such as sensors, push buttons, etc) and controlling output signals (such as sirens, lights, LEDs, etc). These functions are easily implementable in an embedded processor. 4414 Microcontroller is used in this project as it is best suited for security systems
Our design involves a combination of hardware and software. The control functions were programmed in assembly language and downloaded into the FLASH memory on the microcontroller. The hardware consisted of circuitry to run the siren and to simulate the sensors which trigger the alarm. In addition, we designed hardware to provide the necessary power and voltage levels to all the components.
