Question

solve d) and e)

(d) Write the C subroutine named "Indicator" that will control the RGB color as follows: Yellow - Ready (To make yellow R and G should light up) Green-Unlock Red-Lock (e) Write the main program that performs required function of the ATmega32 system using the subroutine "lock_Delay", "Indicator" and "3Second_Delay". Initially the RGB is set to Yellow when the system RESET. The system will unlock once a High signal is received from the Fingerprint Sensor, turn the RGB to Green, then wait 3 seconds before locking back and turning the RGB to red.

FINAL EXAMINATION Q.6 Referring to the ATmega32 Smart Door Lock system in Figure Q.6(a), answer the following questions. On RESET or Power ON the system will continuously display the color 'Yellow' on the RGB LED indicating system is ready. The 'lock driver' require a high signal for 250ms to fully unlock/lock the door. TIMERO is used to implement the 250ms delay. Another timer, TIMERI is used to implement a delay to re-lock the door after 3 seconds. Every time the door is unlocked; the system waits 3 seconds before locking it back. Three subroutines named "lock_Delay", "Indicator" and "3Second Delay" will be used.
