hi there,
i wanna ask u guys about how to program a system that can detects time when someone key in the password on lcd. And also using the timer to detects when that person go out. This is for my project. Please send me the program not the C programming. My board is 8051 intel 8 bit board.
This is the question. When someone key in the passwordon lcd, it will show up on lcd.Then when the password right, the green led light up. If the password is wrong, then the red light up, the person should enter the password again. If, the person come on time, the green light will light up, then person who come late for first time, the yellow light will light up, and last if the person come late for many time, the red light up for 10 times and the buzzer will sound.
TQ for helping me.
