I'm currently trying to write the code for an array of pressure sensor; 3x3 to start. It is pretty simple for Arduino to read the voltage values from multiple "fsr402 pressure sensor". However I would want to convert the x and y cursor of the intensity chart as like a coordinate system, and the z value display in different color. How should I change the intensity chart to what I like? Also, can this show in a 3D graph as well? each sensor should be display like a pixel. I have attach the code here, as well as the picture that I would like to show.
