Digital Lecture 08

This is the code for the Arduino:

int ledPinArray[4] = {29, 30, 31, 32};
int ledTotal = 4;

int potVal = 0;

void setup() {
  Serial.begin(9600);
  
  for(int i = 0; i < ledTotal; i++){
    pinMode(ledPinArray[i], OUTPUT);
  }
}

void loop() {
  
  for(int i = 0; i < ledTotal; i++){
    potVal = analogRead(A14);
    Serial.write(i);
    digitalWrite(ledPinArray[i], HIGH);
    delay(potVal);
    digitalWrite(ledPinArray[i], LOW);
  }


}

This is the code from Processing (I wasn’t sure how to copy the HTML from Processing, it was grayed out for me)

import processing.serial.*;
int inputVal = 0;

Serial teensySerial;

void setup(){
frameRate(30);
size(500, 500);

//printArray(Serial.list());

String usbPortName = Serial.list()[7];
print(usbPortName);
teensySerial = new Serial(this, usbPortName, 9600);
}

void draw(){
if(teensySerial.available() > 0){
inputVal = teensySerial.read();
}

if(inputVal == 0){
background(255, 255, 0);
}

if(inputVal == 1){
background(255, 0, 0);
}

if(inputVal == 2){
background(0, 255, 0);
}

if(inputVal == 3){
background(0, 0, 255);
}

}
