Task 1 - Soldering prerequisites
Introduction
Soldering is a process used to join two or more metal components together by melting and flowing a filler metal (solder) into the joint. It is commonly used in electronics for connecting components on circuit boards.
Materials Needed
- Soldering Iron: A tool that heats up to melt solder.
- Solder Wire: The filler metal used for making connections.
- Flux: A substance that helps in the soldering process by cleaning and facilitating the flow of solder.
- Sponge or Tip Cleaner: For cleaning the soldering iron tip.
- Safety Gear: Safety glasses and proper ventilation to protect eyes and lungs.
Steps
1. Setup
- Place the soldering iron in a holder.
- Turn on the soldering iron and allow it to reach the operating temperature.
2. Clean the Tip
- Wipe the soldering iron tip on a wet sponge or tip cleaner to remove any oxidation.
3. Apply Flux
- Apply a small amount of flux to the joint to be soldered.
4. Heat the Joint
- Touch the soldering iron to the joint, heating both the components and creating a thermal bridge.
5. Feed Solder
- Once the joint is heated, touch the solder wire to the joint, allowing it to melt and flow into the connection.
6. Remove Solder and Iron
- Remove the solder wire first and then the soldering iron. Allow the joint to cool without moving the components.
7. Inspect
- Check the solder joint for a smooth, shiny appearance, indicating a good connection.
Conclusion
Soldering is a valuable skill for electronics enthusiasts. With practice, you can achieve strong and reliable connections for your electronic projects.

Task 2 - Working with pandas and matplotlib
Now in this task we needed to work with pandas and matplotlib this is we can say plot data so i used pycharm and first imported matplotlib and pandas then did the code part where i gave all the inputs of the respective axis and the executed the code and the respective outputs are shown in figure
All the pictures and code are given int my common task repository:https://github.com/sai282828/MARVEL-COMMON-TASK-REPORT-PICS.git
Task 3 - Ubuntu
So using the basics of ubuntu
to create folder name i used command:mkdir
then i used the command: cd
now i created a blank file and listed them using the command: touch and 1s
lastly we needed to create 2600 files
now we need to concatenate two files command used :cat

Task 4 - Speed Control of DC Motor
Speed control of dc motor this task i read the provided article and got to know we can control the speed of motor by controlling the pmw output also got to know that the motor driver allows the speed and direction control of 2 dc motors at a time then with the help of a marvel member i connected the circuit here is the video the speed control
Connect the components as follows:
- Connect the potentiometer:
- Connect one end to 5V on the Arduino.
- Connect the other end to GND on the Arduino.
- Connect the middle pin (wiper) of the potentiometer to analog pin A0 on the Arduino.
- Connect the L298N motor driver:
- Connect the input pins IN1, IN2, IN3, and IN4 to digital pins on the Arduino (e.g., D8, D9, D10, D11).
- Connect the ENA and ENB pins on the L298N to PWM pins on the Arduino (e.g., D5, D6).
- Connect the DC motor to OUT1 and OUT2 on one side of the L298N.
- Connect the power supply to the L298N.

Task 5 - Toggle LED using esp 32
The learning objective was to build a web server that controls ESP32 outputs pins. Here we are using LED for executing this project. I started by building the circuit. I connected two LEDs to the ESP32 as shown in the following diagramm – one LED connected to GPIO 26, and the other to GPIO 27. then copied the code and uploaded in arduino and made the necessary cahnges to get the required output.

Task 6 - Tinker cad
Started by creating a tinkercad account and got to know all the basics where we could create 3d models circuits etc then for creating a circuit where the ultrasonic sensor detects the distance so the components used were arduino a lcd display , sensor and connecting wires here is the link to the completed circuit.

Task 9 - K-Maps and logic circuit
In this task we have to make a burglar alarm circuit to detect when there is an attempt to burglary so we used a truth table where alarm rings only when burglar enters ,but the alarm doesnt ring when both burglar and owner come in. Now using tinkercad i designed a circuit where it detects the burglar entry. this is the link

Task 10- 3D PRINTING
In this task we have to learn what is a 3d printer and how it works and its usage in real life tasks
1 .Designing: Start by creating or downloading a 3D model of the object you want to print. You can use various software such as Tinkercad, Fusion 360, or Blender to design your model. Alternatively, you can download pre-made models from online repositories like Thingiverse or MyMiniFactory.
2. Preparing the Model: Once you have your model, you need to prepare it for printing. This involves slicing the 3D model into thin layers using slicing software like Cura, Simplify3D, or PrusaSlicer. The slicing software generates a G-code file that contains instructions for the printer on how to print each layer.
3. Setting Up the Printer: Turn on your 3D printer and ensure that it is properly calibrated and leveled. Load the filament (the material used for printing) into the printer's extruder according to the manufacturer's instructions. Also, make sure the print bed is clean and properly heated if required by your filament type.
4. Loading the Model: Transfer the G-code file from your computer to the 3D printer. You can do this by connecting your computer directly to the printer via USB or by using an SD card.
5. Starting the Print: Using the printer's interface, select the G-code file you want to print. Adjust any settings such as print speed, layer height, and temperature as needed. Then, start the print job.
6. Monitoring the Print: During the printing process, monitor the printer to ensure that everything is running smoothly. Check for any signs of issues such as warping, stringing, or layer adhesion problems.
7. Removing the Print: Once the print is complete, carefully remove the printed object from the print bed. Use a scraper or spatula to gently pry it off, taking care not to damage the print bed or the object itself.
8. Post-Processing: Depending on the quality and intended use of the print, you may need to perform post-processing steps such as removing support structures, sanding, painting, or applying other finishes.
9. Cleaning Up: Finally, clean up the printer by removing any leftover filament or debris, and make sure to turn it off properly.
By following these steps, you can effectively use a 3D printer to bring your digital designs to life.
