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.
"My board is 8051 intel 8 bit board"
You need to specify the full part number, including all prefix and suffix letters and numbers. Is it a genuine Intel chip?
You need to provide full details of what else is on the board - memory, etc.
"When someone key in the password on lcd"
What LCD - manfacturer? part number? How is it connected to the 8051?
How can the user "key in" anything on the LCD? Is it a touch screen?
What is the nature of the password - digits only? letters? or what?
"when the password right
How will the system know this?
"the green led light up"
What green LED? How is it connected to the 8051?
"the red light up"
What red LED? How is it connected to the 8051?
"If, the person come on time"
How will the system know this? How will the person be identified - you have only mentioned a password...
"come late for first time"
"yellow light will light up"
What yellow light? Is this also an LED, or something else? How is it connected to the 8051?
"the buzzer will sound"
What buzzer? How is it connected to the 8051? What is required to drive it?
