Hi everyone.
I've an arduino that send the value of a potentiometer over serial and i want to use this code to visualize this data on the screen:
import processing.serial.*; Serial port; // Create object from Serial class float val; // Data received from the serial port int x; float easing = 0.05; float easedVal; void setup() { size(440, 440); frameRate(30); smooth(); String arduinoPort = "COM5"; port = new Serial(this, arduinoPort, 9600); background(0); } void draw() { if ( port.available() > 0) { // If data is available, val = port.read(); // read it and store it in val val = map(val, 0, 255, 0, height); // Convert the values } float targetVal = val; easedVal += (targetVal - easedVal) * easing; stroke(0); line(x, 0, x, height); // Black line stroke(255); line(x+1, 0, x+1, height); // White line line(x, 220, x, val); // Raw value line(x, 440, x, easedVal + 220); // Averaged value x++; if (x > width) { x = 0; } }
