Password Protected Security System

Aimed at implementing a Password-Protected Security System on TinkerCad which prompts the user to input a password using Keypad and checks whether the typed password matches to the original password set by the owner, in which case a Green LED lights up and a low pitch buzzer sound is produced and a welcome message is shown on the Serial Monitor, otherwise a Red LED light up and a high pitch alarm sound is produced to alert others and a Warning message is shown on the Serial Monitor.

Hardware Requirements

• Arduino Uno
• Keypad
• Breadboard
• Piezo
