This project presents a real-time, non-invasive glucose monitoring system using an Arduino microcontroller, a TFT display, a DF Player Mini audio module, and a vibration motor to provide multimodal feedback. A non-invasive glucose sensor measures glucose levels, which are displayed on a TFT screen with color-coded indications: blue for low, green for normal, and red for high glucose levels. Additionally, a speaker announces the glucose measurement aloud, enhancing accessibility. A vibration motor provides haptic feedback—intermittent vibrations for low glucose, no vibration for normal, and a long vibration for high glucose. This system enhances user awareness through visual, auditory, and tactile cues, making glucose monitoring more intuitive, user-friendly, and comfortable without the need for finger pricking.    

Objectives:

1. Display Glucose Levels Clearly –Show glucose readings on a TFT screen with color codes:

• Blue for low
• Green for normal
• Red for high

2. Read Glucose Aloud –Use a speaker (DFPlayer Mini) to announce the glucose level.
3. Provide Vibration Alerts –Use a vibration motor for alerts:

• Intermittent vibrations for low glucose
• No vibration for normal
• Long vibration for high glucose

4. Make It Easy to Use –Replace the LCD with a TFT screen for better visibility.
5. Ensure Portability –Use Arduino and compact components for an efficient and portable design.
