Sign Language to Speech Glove 🤖🧤🔊

This Arduino-based project converts sign language gestures into speech using flex sensors and a DFPlayer Mini audio module. It is designed to assist individuals with hearing or speech impairments by providing an accessible, offline communication tool.

👨‍💻 Project Description

• Microcontroller: Arduino (Uno/Nano)
• Sensors: 5x Flex Sensors (connected to A0–A4)
• Audio Output: DFPlayer Mini with microSD card and speaker
• Communication: Offline, no internet required
• Libraries Used:
  • SoftwareSerial.h
  • DFRobotDFPlayerMini.h

Each finger is mapped to a specific audio track that plays when the finger is bent beyond a calibrated threshold.

🛠️ Features

• Calibrates baseline values for flex sensors at startup
• Detects bending of each finger individually
• Plays pre-recorded audio clips corresponding to each gesture
• Ignores further input while audio is playing
• Displays readings and threshold status in Serial Monitor
