TASK 1: 3D Printing

Objective: To understand the working of 3D printer, from online sources. To learn about the Bed temperature and other priner settings.
Outcomes&Learning:

1.PLA(Poly latic acid):

one of the most widely used plastics in the additive manufacturing sector. PLA is often considered to be a more sustainable thermoplastic since it does not come from finite resources, as is the case with petroleum, but is sourced from natural and renewable resources.

2.Bed Temperature:

PLA/PLA+ can be printed on an unheated bed, for best results we can maintain the bed temperature 50°C-60°C.

3.PLA prints best when rapidly cooled with the aid of your extruder's fan. This will ensure a clean, crisp layers with neat details. For the best surface resolution possible, set the extruder fan speed to 100%

4.Printing Speed:

For the better results from the 3D printer we should the speed at 55mm/s or lesst to achieve great surface resolution.

5.Post printing procedures:

a.Joining 3D printed parts
Cyanoacrylate glue (superglue) or two-stage epoxies are a great choice when joining PLA parts.
b.Painting
Except Nylon and PETG allmost all 3D printed parts can be painted.
c.Sanding
PLA parts with progressively finer grades of sandpaper can result in super smooth surface finishes, but sanding process should be done slowly to prevent parts from breaking and melting because of the friction.
Due to time constraint on the lab i missed to print a model.In future i defenately print a model.

TASK 2: Kaggle Contest

Objective: To make a account in kaggle, visit to website and participate in machine learning competation. fist challenge is titanic ML competation and familiarize ourselves in the kaggle platform works. the competation is about to use machine learning to calculate the number of passengers survived in titanic shipwerk.

TASK 4: Writing Resource Article Using Markdown

Objective: To write an technical resource article Using markdown language.
Outcomes&learning:

I Wrote a resource article on the first mission by the ISRO (Indian Space Research And Organisation) click Here To view my resource article

TASK 5: Tinkercad

Objective: To create an account in the tinkercad and make simple circuit to estimate the distance between the ultra sonic sensor and object.
Procedure:
components for the task The connections are made as shown in the circuit diagram The Look after connection Outcomes&Learning:

1.working of ultrasonic sensor

Ultrasonic sensors are electronic devices that calculate the target’s distance by emission of ultrasonic sound waves and convert those waves into electrical signals. The speed of emitted ultrasonic waves traveling speed is faster than the audible sound.
To know the distance between the target and the sensor, the sensor calculates the amount of time required for sound emission to travel from transmitter to receiver. The calculation is done as follows:
D=T*c/2
where, ‘T’ corresponds to time measured in seconds
'c' corresponds to speed of sound= 343 m/s
Ultrasonic sensor Working Principle
The working principle of the ultra sonic sensor is same as radar or sonar it produces high frequency of sound and analyze the echoes by sensors.

TASK 6: Speed control of DC motor by using L298N driver

Objective:
Understand the control DC motors using the L298N motor driver and the Arduino board. Using an UNO and H-Bridge L298N motor driver, control the speed of a 5V motor.
Procedure:
components required for the project connections are made as shown in the circuit diagram The circuit Look after all connections. Outcomes&Learning:

1.working of L298N motor driver

learnt about various parts and functions of the L298N Motor driver\

2.Speed Controlling Using an L298N Motor Driver

The speed of a DC motor can be controlled by changing its input voltage. A widely used technique to accomplish this is Pulse Width Modulation (PWM). PWM is a technique in which the average value of the input voltage is adjusted by sending a series of ON-OFF pulses. This average voltage is proportional to the width of the pulses, which is referred to as the Duty Cycle. The higher the duty cycle, the higher the average voltage applied to the DC motor, resulting in an increase in motor speed. The shorter the duty cycle, the lower the average voltage applied to the DC motor, resulting in a decrease in motor speed. Note: The pins in L298N driver which are responsible for speed control are ENA & ENB, these pins should be compulsorily connected to the PWM (~) ports of the Arduino UNO, so that PWM takes place.

TASK 7:LED Toggle Using ESP32

Objective:
Learn the working of an ESP32 and create a standalone web server with an ESP32 that controls the LED connected with ESP32 GPIOs.
Procedure:
Required components :
1.Two Resistors of 220Ω
2.One ESP32
3.Two LED Lights
connections are made as shown in the circuit After feeding the required code into the ESP32 microcontroller enter the mobile hotspot credentials into the code & change the baud rate to 115200, later during the compilation of the code when you receive an IP address, paste the same into your browser and toggle the LED using the same website.

video of the task in lab.

TASK 8: Soldering Prerequisites

Objective:
To Learn about the soldering equipment and perform basic soldering on a perf board, for example a LED circuit.
Outcomes&Learning:
It was my first experience with soldering of an LED light in the circuit.The precautionary thing is the temperature is to high so we should be careful while performing the task and wash our hands after soldering because the materials like alloy of lead.
