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: They fuel your body with energy. Found in foods like grains, potatoes, and fruits

Proteins: They help build and repair muscles, tissues, and help the immune system. Found in meat, beans, eggs, and nuts.

Fats: Provide long-term energy, protect your organs, and help absorb nutrients. Sources include oils, butter, and seeds.

Vitamins: Essential for growth, immunity, and energy. Found in vegetables, fruits, and dairy.

Minerals: Important for things like bone health and nerve function. Found in things like salt, milk, and leafy greens.

Water: Keeps you hydrated, aids digestion, and helps regulate body temperature. It’s found in water, fruits, and veggies.




● 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)

  Title:    Simple On/Off Control Using MIT Inventor App Introduction : Purpose :  Simplifies inventory management for small businesses. "Bulb On or Off" System :   Items are marked as "on" (available) or "off" (out of stock) for easy tracking. Manual Input :  Users can manually add inventory details such as name, quantity, and price. Inventory Status Overview :  A dashboard provides real-time updates on stock availability. User-Friendly :  Designed for ease of use, even for non-technical users. Efficient Tracking :  Helps businesses monitor inventory levels and manage stock status quickly and effectively.     Components:                Bulb A 105-volt bulb is designed for systems with 105V electrical supply. It provides efficient and reliable lighting for specialized applications. Commonly used in industrial, commercial, or international settings with specific voltage need...

  Project Name : Scratch…. Basic Information about  Scratch ( Block Coding ) Open the scratch website. Create the account for g-mail . choose a Scratch username and a password. Mainly 3 option Code, costumes, Sound. Elements Code: Motion, Event, Controls. Costumes: Fill, Outline, Position. Sound: Variety of sound. like-( animal voice) Then Insert the code block on empty space. Make the story, Games, Animation, Make the instruments Starting of the coding event block is important in event blocks like when the green flag clicked or space button is pressed then insert on blank space then code will run.  ****Code Works slide 1 **** ****Output of slide 1**** ****Code Works slide 2 **** ****Output of slide 2****
