Actively engage in college-level hackathon and technical activities.
Participated in codefurry 8.0 powered by ARTPARK, 1-HUB @IISC,the 8th Annual level Hackathon conducted by IEEE UVCE
Improved communication, problem-solving, and placement readiness.
🖼️ Certificate: 
To create an account on TinkerCad and get familiar with basic components of circuits. and make a simple circuit which measures distance of an object from the ultrasonic sensor.
TinkerCad is an online 3D modelling and circuit tool. I learnt about microcontrollers and ultrasonic sensors and I have successfully made a distance measureing circuit using Arduino UNO and Arduino IDE(how to upload the code)
Link to simulate my task.(https://www.tinkercad.com/things/4glqSoWZSg4-vasanths-tinkercad-task-level-0)

to learn how to write the report
MQ135 is a low-cost semiconductor gas sensor used to detect a wide range of harmful gases in the air such as ammonia (NH₃), nitrogen oxides (NOₓ), alcohol, benzene, smoke, and carbon dioxide (CO₂). Component Overview Sensor Type: Chemical / Semiconductor
Features: High sensitivity to multiple gases Low cost Long life and stability
MQ135 uses SnO₂ (Tin Dioxide) which changes resistance when exposed to gases. In clean air, the sensor has high resistance. When polluted gases are present, the resistance drops, and this change is converted into a voltage signal. HERE IS THE PIC WHICH I REFERED TO KNOW ABOUT IT report:https://github.com/vasanth18-shetty/data-sheet-report-writing-vasanth-/commits?author=vasanth18-shetty
