p5 Example for Arduino Parsing multiple values (controlling 2 arduino outputs with p5 while also controlling p5 with 3 arduino inputs )

Arduino example below:

#include <Servo.h>

Servo motor;
int brightness = 255;
int angle = 0;

int counter = 0;

void setup() {
  Serial.begin(9600);
  pinMode(2, INPUT);
  pinMode(3, OUTPUT);
  motor.attach(9);
  Serial.setTimeout(10);
}

void loop() {
  int pot = analogRead(A0);
  int light = analogRead(A1);
  int button = digitalRead(2);

  if (Serial.available() > 0) {
    //int reading = Serial.read();
    int reading = Serial.parseInt();

    if (counter == 0) {
      brightness = reading;
      counter++;
      Serial.print(pot);
      Serial.print(",");
    } else if (counter == 1) {
      angle = reading;
      counter++;
      Serial.print(light);
      Serial.print(",");
    } else if (counter >= 2) {
      Serial.println(button);
      counter = 0;
    }
  }
  analogWrite(3, brightness);
  motor.write(angle);
}

Code from Class

int button;
int pbutton;
int led1 = 3;
int led2 = 4;
int led3 = 5;
int counter = 0;


void setup() {
  Serial.begin(300);
  pinMode(2, INPUT);
  pinMode(led1, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);
  pbutton = digitalRead(2);
}

void loop() {
  button = digitalRead(2);

  if (pbutton != button) {
    if (button == 0) {   
       counter++;      //not pressed
    } else if (button == 1) {  
      // pressed but do nothing for now
     
    }
    Serial.print("previous button: ");
    Serial.println(pbutton);
    pbutton = button;
  }

  if (counter == 0) {
    digitalWrite(led1, HIGH);
    digitalWrite(led2, LOW);
    digitalWrite(led3, LOW);
  } else if (counter == 1) {
    digitalWrite(led1, LOW);
    digitalWrite(led2, HIGH);
    digitalWrite(led3, LOW);
  } else if (counter == 2) {
    digitalWrite(led1, LOW);
    digitalWrite(led2, LOW);
    digitalWrite(led3, HIGH);
  } else if (counter == 3) {
    digitalWrite(led1, LOW);
    digitalWrite(led2, LOW);
    digitalWrite(led3, LOW);
  }


  if (counter > 3) {
    counter = 0;
  }

Tips for using this site:

Tips adopted and amended from Jeff Feddersen:

With the ITP site, we’ve tried to do two things:

Provide a week-by-week syllabus for the semester that takes you through the physical computing material in a logical progression. Each week has clear tasks, assignments for the following week, and links to labs, write-ups, and videos that support or explain the current material. Follow along here and you’ll be fine. A more concise table view can also be found here
Provide an organized set of materials covering the core physical computing topics, to serve as a first resource for any questions you may have as you study the subject. These live under the Topics, Videos, Resources, and Labs tabs. These materials are also linked to from the syllabus, but here they’re organized by subject matter, whereas the week-by-week syllabus is chronological. Many of these resources are also not assigned or covered in labs so there are plenty of extras that are intended to help as you need it, or provide a starting point for something you may want to use later.

Doing the labs:

Please make sure to budget enough time to read through each lab before plugging things in. Read everything first without trying to follow along. Then re-read and follow the appropriate steps with your kit and code in front of you.
Class is flipped so the idea is to do the labs, write down any questions and bring those questions to class. We will discuss an review in class before moving to new content.
If you are having a lot of success with the labs and have no questions, try to figure out next steps eg”How can the lab be applied creatively or taken further?”. Apply what you learned to a mini project or question. Questions can be creative or technical.
Bring your kits to class. We will often do things in class and use parts from the shop
There are parts in the labs that are not in the kits! These parts are in the Yellow bins in the shop.
I recommend doing your labs at ITP, we have a lot of resources and things that are hard to find in the outside world.
Make sure you know what you need for the labs if you are not doing homework at ITP
Talk to Adrian at the front desk to get a red bin. These are used to store things on the floor Adrian can help you get a red bin and a locker if you want one. You can also email him am13084@nyu.edu
