How well did you study the tutorials on analog use in the Arduino? How about: https://www.arduino.cc/en/Tutorial/AnalogInput. You might find your answers here.Paul
I read through the whole document but still the values I am getting don't make sense. It's not that there are any problems with my breadboarding. Can you please help?
Now you are using the analog pins, what is being returned for a,b,c,d? Surely you have printed those values on the screen.Paul
Currently, I am using graphite (as shown in the video in the previous posts). So pencil graphite thoroughly shaded on paper.
The video did not give the impression that the author's idea worked well.What is the point of this project?
