Hello, We can get data from the web through a process called web scraping, once we have that data we can use the Natural Language API Client provided by Google to get a sentiment score.
with that, we create a graphical display that illustrates these pieces of information.
we can also transmit the data to an Arduino or more preferably an ESP32 that can be connected to the internet without the use of an external module unlike the Arduino, and the ESP32 will control the LEDs according to the average sentiment index.
I plan to use PHP or Python along with javascript/HTML/CSS.
I have experience with web scraping, and I am vice-champion in an international robotics competition so I have experience with Arduino and many other microcontrollers.
