Write an $8051$ embedded C code to count the number of goats passing into a milking parlour

$($Figure $4\mathrm{.}10).$ It is assumed that the sensor arrangement connected to P$1\mathrm{.}1$ gives a $$Logic $0$

output while a goat is passing and a $$Logic $1$ output at other times $($Figure $4\mathrm{.}11).$ Assume that

each goat takes $20$ ms to cross the sensor$.$ Show the count in Port $2.$ Use Keil simulator. Show the

code and output screen shots of simulation using Keil software.
