Task 1: 3D Printing
The objective was to learn how a 3D printer works and the factors on which a model is successfully 3D printed. I used an the Thingiverse website to download the file and creality (software) to scale, support, position and slice the file according to the time limitations. PLA filament was used and bed and nozzle temperatures are set accordingly. I printed the badge associated with the Hand of the King from the series Game of Thrones.
Task 3: Working with Github
The goal of this task was to propose fixation of error in code in main.py file. I forked the repository and cloned it and commited the change which was to remove the +1 from the code . Issued a pull request to adapt change in the code. I faced some confusion initially due to unique terminologies used on this platform.
Task 4: CLI on Ubuntu
The purpose of the task was to understand and use the command line interface offered in OS like Ubuntu and Linux. This was done by creating a folder named test, blank file with the name blankfile.txt using touch command, created 2600 folders with names in specified format. Created a file with names randomtext1.txt and randomtext2.txt in test folder and concatenated using cat command.
Task 5: Kaggle contest
I understood the basics of ML doing this task. I enrolled in titanic ML compitition on kaggle to create a model which predicts the survival rate of passengers. The training accuracy is 92.26% Public score is 0.76555

Task 6: Working with Pandas and Matplotlib
I learnt about the libraries used in python. Matplotlib is one such library which provides visualisation tools, scatter , bar, charts, etc. Matplotlib is imported as plt and values are entered for plotting.
Task 7: Portfolio website
I created my portfolio website using HTML5 and CSS3. I incorporated JavaScript for an interactive website.
Task 8: Resource article writing
I familiarised myself with Markdown and how it formats the text. i wrote an article on the newest Electrical sports car Lamborghini Revulto.
Task 9: Tinkercad
The objective of this task was to have understanding of simulation and microcontrollers. I tinkered a radar system using ultrasonic sensor,a servo motor with a distance range. Here’s the link to the simulation

Task 11:LED Toggle Using ESP32
This task made use of ESP32 microcontroller and 2 LEDs controlled using the same through the Arduino IDE.Recieved the IP adress to control LED state and performed Toggling.The link to it's simulation is given below:
Task 12: Soldering
This task introduced what type of adhesion is adapted in Electronics. It made use of a soldering iron set at a temperature around 200degree Celsius. Flux was used for better flow of the solder. Connections were verified by powering the soldered led and resistor on the PCB
Here's the image
.Task 13: 555 IC Multivibrator
We learnt about Integrated Circuits and timer made for electronic circuits using 555 IC. An oscilloscope was used to read the wave form and detect the duty cycle. This was the task I found a little demanding. Could not get the output at once. Dutycycle obtained was 56.101%
Task 14: K-map
Karnaugh Maps and derivation of the logic circuit. I understood what a K-map meant and scheming one. This makes use of logic gates and the output varies with different combination of gates. I used XOR gate. The circuit alarms when the key is pressed and door is open and when both are closed Here's the link to Tinkercad simulation:
Task 15:Active participation
I participated in Kagada-23 by presenting a poster on Segregation of E-waste using AI&ML.The certificate is attached below.
Task 16:Datasheets Report Writing
L293D Motor Driver Report
Introduction
The L293D is a popular motor driver IC used to control the direction and speed of DC motors. It features an H-bridge configuration, allowing for bidirectional control of two motors independently. This IC is widely used in robotics and automation projects due to its ability to interface with low-power microcontrollers and drive high-current motors.
Specifications
- Operating Voltage: 4.5V to 36V
- Peak Output Current: 1.2A per channel
- Continuous Output Current: 600mA per channel
- Logic Input Voltage: 5V (TTL compatible)
- Enable Pins: Allow for PWM control of motor speed
Internal Structure
The L293D consists of two H-bridges, which are circuits that allow a voltage to be applied across a load in either direction. The IC uses diodes for back EMF protection and transistors for switching.
H-Bridge Configuration
An H-bridge is a simple circuit that allows a motor to be driven forward or backward. It consists of four switches (transistors or MOSFETs) that can be controlled to create different voltage polarities across the motor terminals.
- Forward: Closing switches S1 and S4, while keeping S2 and S3 open.
- Backward: Closing switches S2 and S3, while keeping S1 and S4 open.
Pulse Width Modulation (PWM)
PWM is a technique used to control the speed of a motor by varying the duty cycle of a digital signal. By adjusting the duty cycle, the average voltage and current delivered to the motor can be controlled, thus regulating its speed.
Control Pins
- Input Pins (1A, 2A, 3A, 4A): Control the state of the H-bridges.
- Enable Pins (1, 9): Enable or disable the H-bridge outputs. Can be used for PWM control.
- Output Pins (1Y, 2Y, 3Y, 4Y): Connect to the motor terminals.
Applications
- Robotics
- Conveyor Belts
- Automated Systems
- Motorized Curtains
- CNC Machines
Conclusion
The L293D motor driver is a robust and versatile IC that simplifies the control of DC motors. Its H-bridge configuration and PWM capability allow for precise control of motor direction and speed, making it an essential component in many electronic and robotic projects.
