WEEK 5 : SENSORS AND ACUTUATORS

-


SERVO MOTOR :

In this week, we were introduced to servo motor. We turned it back and forth across 180 degrees by using Arduino tools and following the instructions of our teacher Mr. Carl James. It was very fun because I was controlling hardware using software. 


                                                   


Let me give you a short brief on Servo motor.

Servo motors have three wires : Power, Ground, and Signal. The power wire is typically red, and should be connected to positive pole of your power source. The ground wire is typically black or brown and should be connected to the negative pole of your power source. The signal pin is typically yellow or orange and should be connected to PWM pin on the board and the pin number is 9.


The below pictures shows, how I used my Servo Motor with my Arduino kits.  




This is the code that I used to control the motor.






ULTRASONIC SENSOR :

After the Servo Motor, our teacher introduced us to Ultrasonic Sensor. First, let's discuss a little bit about Ultrasonic Sensor.

An Ultrasonic Sensor is a device that uses sound waves to measure distances. In an Arduino Uno setup, an ultrasonic sensor typically includes a transmitter that sends out ultrasonic pulses and a receiver that listens for the echoes when those pulses bounce back from an object.


We connected the sensor to the Arduino Uno then programmed it and measured some distances with the sensor.





This is the code that I used to control the sensor.




This is the video of what was actually happening.

And all of these interesting and fun things we did in week 5.

Main Project : A Lie Detector

In week 12, our teacher introduced us to our main project. He informed us that we now have a basic understanding of Arduino and encouraged us to apply our knowledge creatively to develop something useful. This project will contribute to our final grading, and upon completion, we will be required to create a video demonstrating its functionality. Additionally, he mentioned that the most innovative projects will be showcased at a science fair, where numerous attendees, particularly school students, will have the opportunity to interact with our products. Following the instructions, we formed groups of three individuals. I, Chowdhury Shakline, along with my friends Neelushan Antony and Mahid Ahmed, constituted one such group. After a week of brainstorming various ideas, we collectively decided to create a lie detector. Initially, we deliberated amongst ourselves regarding the necessary kits, the wiring setup with Arduino, and the coding process. Subsequently, we presented our idea to our ...

Recommender System

This week, our teacher introduced us to a fascinating topic: Recommender Systems. Let's provide you with a brief overview of what a recommender system is and how it works. A recommender system is a type of information filtering system that predicts and suggests items or content that a user might be interested in, based on their preferences, past behaviour, or similarities with other users. These systems are widely used in various online platforms such as e-commerce websites, streaming services, social media platforms, and more. Here's how a recommender system typically works: Data Collection : The system gathers data on user interactions, such as purchases, ratings, views, clicks, likes, and other relevant actions. User Profiling : The system creates profiles for individual users based on their preferences, behaviours, and historical interactions with items or content. Item Representation : Similarly, the system analyses items or content available in the system and represents t...
