RoboSafe - Wireless Controlled Locker with Arduino Mega

RoboSafe is a simple yet effective wireless controlled locker using an Arduino Mega. It can be unlocked via the mobile app, RFID card, fingerprint, and even stream live footage to your device. This project was originally created as part of the National Science Exhibition of India 2022.

Features

• Wireless control of the locker.
• Unlocking options: Mobile app, RFID card, and fingerprint.
• Live video streaming capability.
• Created for the National Science Exhibition of India 2022.

Project Versions

• Version 1: The initial version was created for our internal school round. You can access the code for this version on our v-1 branch.

• Version 2 (Current): The current and final version of the project, which includes enhancements and improvements.
