Nutrients Indicator System

 Title: Arduino-Based Nutrients Indicator System

❖INTRODUCTION:

• In Today’s World, Maintaining ABalanced Diet Is Crucial For Good Health.

Vitamins Play A Vital Role In Our Well-Being, Yet Many People Suffer

From Deficiencies Without Even Realizing It. What If There Was An Easy

Way To Detect Vitamin Levels At Home Or In A Small Clinic Using

Affordable Technology?

• With This Innovation, We Aim To Bridge The Gap Between Technology

And Healthcare, Making Nutritional Analysis More Accessible To Everyone.

Let’s Explore How This System Works And Its Potential Impact On

Everyday Health Monitoring.

❖Components:

• Arduino Uno:

• Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects.

• HC-05 Bluetooth Module:

• The HC-05 is a popular and inexpensive Bluetooth module that allows wireless communication between devices. It's commonly used with microcontrollers like Arduino to add Bluetooth functionality to projects.

• Breadboard:

• A breadboard is a solderless prototyping platform used for building temporary circuits for testing or experimentation. It's characterized by its rows of interconnected holes (called "tie points") that allow you to easily connect electronic components without soldering.

• LEDs:

• Jumper Wires:

• Jumper wires are essential tools for anyone working with electronics, especially when prototyping circuits on a breadboard. 

• Mobile/Laptop for input:

****About PictoBlox****

• PictoBlox is a user-friendly, block-based coding platform designed to make learning to code fun and engaging, especially for beginners. It's similar to Scratch but with some powerful enhancements.

    This Project implemented in the PictoBlox.

❖Working Principle:

How It Works – Simple & Interactive!:

Imagine you’re curious about which foods contain carbohydrates. Instead of

searching through long lists or reading nutrition labels, you simply type

“Carbohydrates” on your laptop or mobile device. And just like magic—LEDs

light up next to foods like tur dal, yogurt, and butter, showing you exactly

where to find them!

Step-by-Step Breakdown:

1. Setting Up the System:

    o We have 10 LEDs, each linked to a different food item like tur

        dal, yogurt, and butter.

    o Everything is connected using a breadboard and an Arduino

        microcontroller.

    o A Bluetooth module lets the system talk to your laptop or phone

        wirelessly.

2. Typing Your Nutrient Query:

    o You enter the name of a vitamin or nutrient (e.g.,

        “Carbohydrates” or “Vitamin A”) into the laptop.

3. The Smart Processing Begins:

    o The Arduino reads your input and checks its stored data to find

        which foods contain that nutrient.

4. The Magic Happens – LED Lights Up!

    o The system sends a signal to light up the LEDs next to the foods

        that contain the nutrient you asked for.

    o If you typed “Carbohydrates”, the LEDs near tur dal, yogurt, and

        butter will glow.

5. Instant Feedback:

    o You immediately know which foods are rich in the nutrient you

        searched for—no complex charts or research needed!

Why This is Awesome?

✔Super Easy to Use – Just type a nutrient name, and the system does the rest!

✔Wireless & Smart – Uses Bluetooth, so no messy wires or complicated

setup.

✔Educational & Fun – Great for learning about nutrition in an interactive way.

✔Customizable – More foods and nutrients can be added in the future.

❖Algorithm:

• Start

• Initialize Serial Communication

❖ Initialize the serial communication for debugging (using Serial.begin()).

❖ Initialize the Bluetooth communication (using Dabble.begin()).

• Set LED Pins as OUTPUT

❖ Set pins 4 to 13 as OUTPUT to control the LEDs.

• Turn OFF All LEDs Initially

❖ Ensure that all LEDs are turned OFF at the start (using digitalWrite(pin,

LOW)).

• Loop Continuously:

❖ Check if Bluetooth data is available:

➢ Use Dabble.processInput() to check if any data has been received over

Bluetooth.

➢ If data is available, proceed to step 6.

❖ If data is received:

➢ Read the received character.

➢ Print the received character for debugging.

▪ This helps in troubleshooting and ensuring the input is correct.

➢ Turn OFF all LEDs to reset the system.

▪ Reset all LEDs by turning them OFF before activating the correct one

based on the input.

➢ Check the received character:

▪ If ‘A’, turn ON Vitamin A LED (Pin 4).

▪ If ‘B’, turn ON Vitamin B LED (Pin 5).

▪ If ‘C’, turn ON Vitamin C LED (Pin 6).

▪ If ‘D’, turn ON Vitamin D LED (Pin 7).

▪ If ‘E’, turn ON Vitamin E LED (Pin 8).

▪ If ‘K’, turn ON Vitamin K LED (Pin 9)

.

▪ Otherwise, print "Invalid Input!" if an unknown command is

received.

• Repeat the loop to check for new inputs continuously.

• End (System keeps running indefinitely).
