Introduction

This project demonstrates how to connect a Flutter application to an Arduino via Bluetooth using the HM-10 module. The Locker Guessing Game is a unique application where you need to guess a number shown in binary form through LEDs. The twist? You have to speak the number out loud! Utilizing advanced speech recognition, the app captures your spoken response, communicates it to an Arduino device via Bluetooth, and checks if your guess is correct.
