#Nutrients in Foods

 Nutrients in Foods (Using Arduino and Scratch with Bluetooth Control)


1. Introduction

● Introduction: Nutrients in Foods

Nutrients are essential substances found in foods that are necessary for the proper

growth, development, and functioning of the human body. They provide energy, build

and repair tissues, and regulate various bodily processes. A balanced diet containing the

right amount of nutrients helps maintain overall health and prevents diseases.

There are six main types of nutrients found in food:

  • Carbs – The main fuel source for the body, commonly found in grains, fruits, and vegetables.
  • Proteins – Crucial for body repair, muscle growth, and overall development, present in meat, eggs,                          legumes, and dairy products.
  • Fats – Provide long-lasting energy, support cell function, and aid in absorbing key vitamins, found                     in oils, nuts, and fatty fish.
  • Vitamins – Organic compounds needed for various body processes, such as immune function and                              metabolism, sourced from fruits, vegetables, and dairy.
  • Minerals – Essential elements that help with bone strength, nerve signaling, and fluid balance,                                    found in foods like dairy (calcium), meat (iron), and bananas (potassium).
    •       Water – A fundamental component for hydration, digestion, and temperature control, available in                       drinking water, fruits, and vegetables



    Introduction: Project


    The project "Nutrients in Foods" utilizes Arduino and Scratch programming to identify

    nutrients present in food samples using an LED-based indication system. A Bluetooth

    module is used to wirelessly send commands to the Arduino, allowing users to toggle

    LEDs corresponding to specific nutrients. This interactive method provides an engaging

    way to learn about nutrient composition in different foods

    2. Components Required

    To build this project, the following hardware and software components are required:

    Hardware: 


    ● Arduino Uno

    ● Bluetooth Module (HC-05) 

    ● LEDs (Red, Green, Blue, Yellow, White)

    ● Breadboard 

    ● Jumper Wires

    ● Power Supply (9V Battery or USB cable) ● USB 2.0 Cable 

    Software: 

    ● Scratch (with Arduino Extension)

    ● Arduino ID 

    ● Bluetooth Serial App (for sending commands)


    4. Working Procedure 

    1. Upload the Scratch-based Arduino code to the board. 

    2. Pair the Bluetooth module with a mobile phone. 

    3. Use a Bluetooth Serial App to send specific commands. 

    4. Based on the received command, the Arduino will turn on the corresponding LED, indicating the nutrient type in the food sample. 

    5. The user can turn off the LED manually via Bluetooth commands.


    CODE WORKS



    5. Conclusion

    This project demonstrates how Arduino, Scratch, and Bluetooth technology can be used to

    build an interactive nutrient identification system. By using LEDs as indicators, users can

    understand food composition in an engaging and practical way. The project can be expanded

    further by integrating sensors to detect nutrient levels automatically.

    #Automatic LED Control Using Solar Power and Battery Backup

    Image
      Introduction With the growing emphasis on renewable energy, integrating solar power into everyday applications is a step toward sustainable living. This project demonstrates how to build an automatic LED control system using a solar cell, diode, switch, LED, photoresistor, and an NPN transistor. The system ensures that the LED glows when solar power is available, while the battery remains off, effectively managing energy usage. Components Required Solar Cell (5V or higher, depending on LED requirements) Diode (e.g., 1N4007 to prevent reverse current) Switch LED (Light Emitting Diode) Photoresistor (LDR - Light Dependent Resistor) NPN Transistor (e.g., BC547) Resistors (as per required values) Battery (Rechargeable, 3.7V or 5V) Connecting Wires Breadboard How It Works Solar Power Supply: The solar cell converts sunlight into electrical energy, providing the primary power source for the LED. Photoresistor (LDR) Detection: The LDR detects ambient light levels. ...
