MARVEL LEVEL 1 REPORT\n\n## KAGGLE - TITANIC SURVIVAL PREDICTION\nKaggle is an online community of data scientists and machine learning practitioners. Kaggle allows users to find and publish data sets, explore and build models in a web-based data-science environment, work with other data scientists and machine learning engineers, and enter competitions to solve data science challenges.\n

\nTitanic survival prediction is a contest on Kaggle, where data set of the survivors was given. The dataset was divided into train and test data frames.The train dataset which had information on the survivors of titanic was used to make a prediction model. This model was used on the test dataset to obtain the chances of survival.\n

\n## PANDAS AND MATPLOTLIB\nPandas is a python library used for working with datasets. It allows us to analyze data and make conclusions based on statistical theories.Matplotlib enables visualization of data via graphs.Matplotlib consists of several plots like line, bar, scatter, histogram\n

\nDataset on world population over the course of seven years (1960-1967) was used to plot bar graph, line graph and scatter plot. The number of countries (the number of rows) was reduced to ten to ensure clearer and easier to read graphs.

\n## SOLDERING\nSoldering is a process in which two or more items are joined by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal.

\nTools for soldering consists of : \nSOLDERING IRON-A soldering iron is a hand tool that plugs into an electrical outlet and heats up in order to melt solder around electrical connections. \nSOLDER-Solder is a metal alloy material that is melted to create a permanent bond between electrical parts. It comes in both lead and lead-free variations.Inside the solder core is a material known as flux which helps improve electrical contact and its mechanical strength.\nSPONGE-Using a sponge will help to keep the soldering iron tip clean by removing the oxidation that forms. \nSOLDERING IRON STAND-This stand helps prevent the hot iron tip from coming in contact with flammable materials or causing accidental injury to your hand. \nSOLDER WICK-It is used to desolder Heat your soldering iron and touch the tip to the top of the braid. This will heat the solder below which will then be absorbed into the desoldering braid. You can now remove the braid to see the solder has been extracted and removed.

\nPROCESS OF SOLDERING-\nThe component to be soldered is placed on the circuit.\nPlace the solder close to the joint to be soldered.\nThe soldering iron is used to melt the solder. \nThe joint is soldered.

\n## TINKERCAD\nTinkercad is an online platform that enables us to build circuit code functions and stimulate it to ensure it works. It fastens the process of building a working blueprint and saves time.A ultrasonic sensor was used to determine the distance of an object and the distance was displayed on a LCD screen.The sensor and LCD screen was connected to an arduino board and the code was uploaded to the board.

\n\n## LED TOGGLE\nAn ESP32 was connected to LED lights and the lights were controlled via a standalone webpage. The connection were made first and then the code was uploaded to the ESP32.

\n## GITHUB\nGitHub is a Git repository hosting service. GitHub essentials are: \nREPOSITORY- A GitHub repository can be used to store a development project.It can contain folders and any type of files (HTML, CSS, JavaScript, Documents, Data, Images).\nBRANCH- A GitHub branch is used to work with different versions of a repository at the same time.By default a repository has a master branch (a production branch).New Branches are for bug fixes and feature work separate from the master branch. \nCOMMIT- At GitHub, changes are called commits.\nPULL REQUESTS- With a pull request you are proposing that your changes should be merged (pulled in) with the master.Pull requests show content differences, changes, additions, and subtractions in colors (green and red).\n

\nThe first step to completion of the task was creating a repository. Then pulled the code from Marvel’s repository by creating a branch.The code was inspected and fixed.\nImage of the code\nImage of the code\n

\n## 3D PRINTER\n3D printing is a process of making three dimensional solid objects from a digital file.The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object.Slicing is the process of breaking down a 3D model into thousands of horizontal layers, which can then be printed one layer at a time.\n STL stands for \Standard Triangle Language" and "Standard Tessellation Language".STL file of the object to be printed was downloaded from thingiverse.The file was then sliced using Creality.The file was loaded to the printer using a SD card.

\n## MARKDOWN LANGUAGE\nMarkdown is a simple syntax that formats text as headers, lists, boldface, and so on.A document on C++ was created on VS Code using markdown.It has been uploaded on marvel website as a resource article.\n

\n## API\nAPI stands for application programming interface. Python was used to create an interface to generate random text. The user must enter a prompt for which text will be generated.\nImage of the code\nImage of output"
