TASK 1: 3D Printing

This task involved exploring the basics of 3D printing, including understanding how 3D printers work and the role of STL files in the process. I learned to use slicing software like Ultimaker Cura to convert STL files into G-code for printing. I also studied key printer settings such as bed temperature and nozzle temperature.After the duration of printing time(1 hour 2 minutes) I got my model ready.

TASK 2: API

In this task I created a weather web application where users can fetch the weather data using the search option. Application Programming Interface(API) is a set of rules and protocols that allows different software applications to communicate with each other. I used free API which are available in web. I used python for entire tasks from GUI for fetching API. Github link :https://github.com/ShashankMk031/weather_api/tree/master

TASK 3: Working with Github

In this task Familiarized myself with GitHub. Cloned the given repository to my account using the git command git-clone. Corrected the error. Saved and committed using git command git-commit. Pushed into my repository using the git command git-push. Next, I pulled a request to merge with the main branch. Link :https://github.com/ShashankMk031/git-task

TASK 4: Get familiar with the command line on ubuntu and do the following subtasks:

In this task, I learned basic Ubuntu command line operations. I created a folder named test123 and added a blank file using mkdir and touch commands. I created 2600 folders with alternating names using mkdir {A..Z}{0..9}{0..9}. Then, I created two text files (file1.txt and file2.txt) and concatenated them using the cat command.

TASK 5: Kaggle contest

Under this task I made a kaggle account and learnt how to work with the projects related to data science and machine learning. And Participated in the Titanic ML competition.This competition is simple: use machine learning to create a model that predicts which passengers survived the Titanic shipwreck and compare it with actual data . Here I used pandas and matplotlib to visualize and analyze the train.csv file . I got a score of 0.72009, it means that the model is 72% accurate with the actual data.

TASK 6: Working with Pandas and Matplotlib

Learned how to use NumPy and Matplotlib to plot graphs.

Created: A scatter plot . A bar graph . A line plot.

TASK 7: Create a Portfolio Webpage

For task 7 I have created my portfolio page using HTML( Hyper Text Markup Language) and CSS( cascading Style Sheet) . You can view it here

TASK 8: Writing Resource Article using Markdown

Hologram the future of Visual Communication

Holography is revolutionizing the way we interact with visual content. By creating 3 D images that appear to float in space , they are applied in entertainment industry, education , designing and more .

TASK 9: Tinkercad

Created a TinkerCad account. learnt how to use the circuits. Constructed a circuit that measures distance using an Ultrasonic sensor and Arduino

TASK 10: Speed Control of DC Motor

In this tassk, I explored how to control the speed of a 5V DC motor using an L298N motor driver and an Arduino UNO.I simulated the system on Tinkercad before testing it with real hardware.The circuit was first simulated on Tinkercad, where I wrote code to adjust the motor speed. After successful simulation, I built the circuit using real hardware.

TASK 11: LED Toggle Using ESP32

Learned the working of ESP32. Built a standalone web server that controls an LED connected to ESP32 GPIOs. Used Arduino to code it.

TASK 12: Soldering Prerequisites

In this task learned how soldering works and about soldering equipment like soldering gun, flux, and solder. Soldered an LED and checked its function using a battery.

*TASK 13:Design a 555 astable multivibrator *

In this task we needed to design a 555 astable multivibrator with duty cycle 60%,using 10 kilo ohms and 20 kilo ohms resistors. Set up the circuit on a breadboard and observed the output on the DSO.

TASK 15: Active Participation

TASK 16: Datasheets report writing

L293D Motor Driver Summary

The L293D is a widely used motor driver IC that allows for the control of motors in various electronic applications. It provides a simple way to control the direction and speed of DC motors, stepper motors, and other types of motors. This report will cover the working principle of the L293D motor driver.
