„hihihide behind the clouds“ – the most minimalistic one poti game

This first minimal approach to interface alternative user interface elements, like potentiometers or sensors comes along with a proper oldschool Firmata/Arduino/Processing pipeline. Also check out the minimalistic custom firmata for flickerless LED action 😉 >>> https://turboflip.de/processing2arduino-firmata-basic-setup/

Assets needed:

import processing.serial.*;
import cc.arduino.*;
Arduino arduino;
  
int led_pin = 10; // testLED on pin 10!
int analog_pin = 0;  // analog input from poti on A0
  
  
void setup() {
    
 // fullScreen();
  size(600,300); // setup the stage size
  background(22);
   
  // Prints out the available serial ports.
  println(Arduino.list());
   
  // initalize Arduino (  pick first COM device > need to be changed if u have more! )
  arduino = new Arduino(this, Arduino.list()[1], 57600);
   
  // set the LED pin to output mode
  arduino.pinMode(led_pin,Arduino.PWM);
      
  print(" >>> --- Arduino says Hello ;) -- >>> ");
  println(arduino);
