hello..
I am working a car parking monitor system...plz find the attachment with complete details....
i have made few changes..i am not using TSOP RECEIVER in my circuit..i am using simple ir led receiver..
i am making six slots interfacing to micro controller 89s52.
the input pins are 2.0 to 2.6 and output pins are port connected to LCD (jhd 162a 16*2)
i want a program logic for the following
case1:when all parking slots are empty
LCD should display " vacant slots:b1,b2,b3,b4,b5,b6
case2: now a car gets parked in slot b1 (for example)
LCD output should be
empty slots :b2,b3,b4, b5,b6 (exclude b1)
case 3: say the parking slot b1 gets vacant again
b1 should again come in the list..
output on LCD , of empty slots=b1,b2,b3,b4,b5,b6
thanks in advance
