Interactive Meter

For this lab we were required to demonstrate our knowledge of analog input. It was suggested that we could replicate a love meter, so I thought of creating instead an Interactive Meter, that used the same principle. My idea was based on the last step of the first part of the lab, wich had an LED connected to the breadboard (negative lead on outer negative row of the breadboard and positive in one of the inner rows of the breadboard), a 330 ohm resistor conected to the positive lead of the LED and a wire (green) connected to the other lef of the resistor and to the selected pin number in the Arduino Board.

The way the system works is based on an input that comes from the user. This input is measurable because of the force-sensing resistor I used, which permits not only knowing if it is active or inactive, but it also lets us know the intensity of the input. To be able to measure visually this different intensities it was necessary to use various LEDs, in my case, I used 5 LEDs. This ranges were stated in the Arduino code, so that the system could work properly.
