Introduction

For individuals who are blind or have low vision, accessing information about time can be a significant challenge. Conventional analog and digital clocks often rely on visual cues, making it difficult for those with visual impairments to tell the time accurately. To address this need, this final project presents a solution in the form of a blind tool based on the ATMEGA 8535 microcontroller. This innovative tool is equipped with a sound preview feature that enables blind individuals to find out the time with ease and accuracy.

Design and Components

The blind tool is designed from a combination of several essential components, each playing a crucial role in its functionality. The Real Time Clock (RTC) DS1307 serves as a precision time pointer, providing accurate time data. The time data is accessed and written to the RTC DS1307 serially through the I2C (Inter-Integrated Circuit) communication protocol. Furthermore, the IC (Integrated Circuit) WTV Voice Module 020-SD is responsible for translating time data into sound, which is then emitted through a headset. This feature enables blind individuals to perceive the time through sound, making it easier for them to navigate their daily lives.

Programming and Development

The programming of this tool is carried out using the C language, which facilitates the development process. The C language is a popular choice for microcontroller programming due to its simplicity, flexibility, and efficiency. By utilizing the C language, the development process is streamlined, and the tool can be optimized for the specific needs of the blind.
