• Adding CNN Layers
• Adding Output Layers
• Configuring the Learning Process
• Training the Model
• Saving the Model
• Testing the Model

Application Building

In this section, we will be building a web application that is integrated into the model we built. A UI is provided for the user where they can upload an image. The uploaded image is given to the saved model, and the prediction is showcased on the UI.

I have built a web application that is integrated into the model we built. A UI is provided for the uses where he has uploaded an image. The uploaded image is given to the saved model and prediction is showcased on the UI.

This section has the following tasks

● Building HTML Pages:

➤ We use HTML to create the front end part of the web page.

➤ Here, we created html page as index.html.

➤ index.html displays the home page and displays all important details to be known about ECG with choose button

➤ predict button accept input from the user and predicts the values

Plane App

The "Plane App" is a mobile application designed using Mobile App Inventor, offering a user-friendly platform for creating custom Android apps

Overview

The "Plane App" is an exciting mobile game application with three key pages: "Start Game," "Actual Game," and "Game Over." In this immersive gaming experience, users navigate an aircraft through a dynamic environment, aiming to avoid collisions with the screen borders.

Game Pages

1. Start Game: This is where the adventure begins. Users initiate the game from this page.
2. Actual Game: This is the central gaming experience. It features:
   • Directional Controls: Up, down, left, and right buttons provide players with control over the plane's movements.
   • Border Avoidance: The challenge lies in avoiding collisions with the screen borders, requiring quick reflexes and strategic maneuvering.
3. Game Over: This page marks the end of the game. Users can see their final score and decide whether to restart or quit.

Gameplay

The "Plane App" offers a thrilling and visually stimulating gaming experience. Players must skillfully pilot their plane to prevent it from hitting the screen boundaries. This not only adds excitement but also encourages users to hone their avoidance strategies, making each game a unique challenge.

Conclusion

The "Plane App" is an engaging mobile game application that provides an immersive experience with three distinct game pages. Users can enjoy dynamic gameplay with directional controls, testing their reflexes and agility while avoiding screen border collisions. It offers a fun and challenging gaming experience for players of all ages.

Created a List Management App Using Mobile App Inventor

Overview:

In this project, we will explore how to design and build a List Management App using Mobile App Inventor. The app will consist of a main screen with an input box and three primary functionalities: Add, Update, and Delete items from the list. Users can add an unlimited number of text items to the list, update existing entries by clicking on them, and delete items as needed.

Key Features:

• Main Screen with Input Box:

  • The app's main screen provides users with a simple and intuitive interface.
  • An input box allows users to type in text that they want to add to the list.

• Add Functionality:

  • Users can add text items to the list by entering text into the input box.
  • Upon clicking the "Add" button, the entered text will be added to the list, creating a dynamic list of user-defined items.

• Update Functionality:

  • To update an item, users click on the item they wish to edit within the list.
  • After clicking, a text field will appear, allowing them to modify the text.
  • Users can save their changes by clicking an "Update" button associated with the edited item.

• Delete Functionality:

  • Deleting an item is a straightforward process.
  • Users can select the item they want to remove from the list.
  • Clicking the "Delete" button next to the selected item will permanently remove it from the list.

How to Use the App:

Adding Items:

1. Type the desired text into the input box.
2. Click the "Add" button to add the text to the list.

1. Locate the item in the list that you wish to update.
2. Click on the item.
3. A text field will appear for editing.
4. Make your changes and click "Update" to save.

1. Select the item in the list that you want to delete.
2. Click the "Delete" button associated with the chosen item.
3. The item will be removed from the list.

Benefits of the App:

• User-Friendly: The app's user interface is designed to be user-friendly and intuitive, making it easy for anyone to manage their lists.
• Efficient List Management: Users can conveniently add, update, and delete items, ensuring the list remains organized and up-to-date.
• Scalability: The app allows users to add an unlimited number of items to the list, making it suitable for various purposes, from to-do lists to shopping lists.
• Customizable: Users can tailor the app to their specific needs, providing a personalized list management experience.

In conclusion, this List Management App created using Mobile App Inventor offers a user-friendly and flexible solution for organizing and managing lists. Whether it's a simple to-do list or a more complex inventory, this app empowers users to easily add, update, and delete items, all without the need for extensive coding skills. It's a practical tool for maintaining and customizing lists for various purposes.

Bus Identification for Visually Impaired People - Personal Assistant Segment

When a Visually Impaired Person reaches the Bus Stop by using the RFID given by the authority is placed in the RFID Reader of the Personal Assistance Segment Prototype shown above Fig 5.2 which is connected to the Power Supply. RF Reader will bypass the information of the RFID to Zigbee if it is a valid access card(AUTHORIZED CARD) and it is alerted by a Buzzer or less by “UNAUTHORIZED CARD” played by the voice playback module. In the case of Authorized card(M12 Bus), the information is carried over to Zigbee which is connected over Arduino Mega. Zigbee stores the information (M12 Bus) and transmits signal to the incoming bus which having Bus Driver Segment Prototype

Bus Identification for Visually Impaired People - Bus Segment

Each Bus will be attached with a Bus Driver Segment Prototype which is connected to the Battery of the Bus as the Power Supply to the prototype. In the LCD display “BUS NO. M12” When the M13 Bus arrives in the range of 30-100m Zigbee gets connected and transmission of information takes place. The Bus Driver is alerted by the LCD that will display “BLIND IS WAITING”. So that he/she will click the reply button to notify the Visually impaired Person in the Personal Assistance Segment. Therefore in Bus Stop by voice playback module the Visually Impaired Person is notified by the audio output as “M12 Bus is near”. Finally, the Visually Impaired Person get to know the bus and reach the bus without anyone's help. The Bus Conductor will make note of total number of Visually Impaired Person riding the bus in a day and submit those notes to the authority
