Discover the magic of DTMF (Dual-Tone Multi-Frequency) technology, where your voice and data travel through the air as special tones. With ToneTalk, sending messages and information is as easy as pressing buttons on your phone. No need for complicated setups – just talk, and let the tones do the talking for you! It’s the simple and efficient way to transmit both voice and data seamlessly you can event transmit data when there is any kind of hindrance (in this project we use water as a hindrance).

This project demonstrates a simple yet effective way to transmit both voice and data using DTMF technology. It finds applications in areas such as telecommunication, remote control systems, and data transfer where a simple and reliable communication method is required.

Working : This project utilizes DTMF technology for voice transmission, providing users with a dial tone feedback when a keypad button is pressed. Additionally, the circuit is designed to play audio from a YouTube video through a buzzer connected to the system.

Operation:

1. Press a button on the keypad to initiate the dial tone feedback.
2. The microcontroller displays the pressed button and triggers the DTMF encoder to generate corresponding dial tone frequencies.
3. Simultaneously, the microcontroller processes audio from a YouTube video and plays it through the buzzer.

This project provides a hands-on experience of DTMF-based voice transmission with additional features like dial tone feedback and YouTube audio playback, enhancing user interaction with the system.
