Access Control System Design in TinkerCad | Interface 4x4 Keypad with Arduino | TinkerCad Project
TinkerCad is a powerful tool for Arduino-based engineering project simulation. Project Functioning:
1. First Arduino Will Read the Keypad for any Input
2. When the password length is 4, Arduino will automatically match the entered password with the saved password,
3. If the password is correct, then the door will be opened else, the display will show, "Wrong Password" and you have to enter the password again.
