You will simulate following scenario: There is a man
who wants to enter his home.
1)When he gets close enough to the door (it means getting into range of PIR sensor), output of PIR
sensor will be HIGH. Getting HIGH output once is enough.
2) He should enter the password of the door using Keypad to get in his house.
3) If password is correct, door will be open using micro servo motor. (It means micro servo motor
will rotate its head left and right).
You will use tinkercad simulation enviroment. I will provide you my account to work on. So you can share finished link with me.
You can see details on attachment.
Budget is 40$
