Let your web application in JavaScript, VueJS or p5js communicate with your Arduino board.
nnarduino
==============
#### Build a bridge between an Arduino Microcontroller and p5js to create Computer Generated Art.
This will let the visitors of your digital exhibition or installation generate graphics and patterns using buttons, sensors, switches, potentiometers, gyroscopes etc.
Please refer to the documentation for more infos.
#### The main concept is:
- Use JSON to communicate between NodeJS or JavaScript and the Arduino Board
- Get the Board connected as fast and smart as possible
- Have autodetect features for the hardware, reducing the need to write long configurations
- Keep the methods to wire a physical sensor to p5js as simple and intuitive as createButton()
- Make it easy to deploy the project as a standalone application, i.e. for exhibits or art installations
#### Example: Simple Push-Button
To demonstrate how easy it is, to connect a sensor with p5.js, have a look at the following sketch. Note that this is not an Arduino Sketch in C++ - it is written in JavaScript with p5js.
The physical button is connected to PIN 2 of the Arduino. To make p5js “watch” the button, all we need to do is write button = connectSensor( SENSOR_BUTTON, 2 ); The library will automatically search for the right port, connect with the Microcontroller, configure the pin and add an EventListener.
In the sketch, pressing the button will reduce the size of the circle on the canvas. Nothing really creative… but it saved you the headache that makes you uncreative!
``
import {sketch} from 'nnarduino/lib/adapter/p5.adapter';
import 'p5/lib/addons/p5.sound';
let button;
function setup () {
createCanvas(400, 400);
button = connectSensor( SENSOR_BUTTON, 2 );
}
function draw () {
background( 255 );
if (button.value() == 1) {
circle( 200, 200, 50 );
} else {
circle( 200, 200, 100 );
}
}
``
#### What you'll need to get started:
| Download | Needed for... |
|------------------------------------------------------------------------------|-----------------------------------------------------|
| NodeJS | npm for installing packages from the command line |
| Arduino IDE | software for uploading scripts to the Arduino board |
| arduino-p5js | the quick-start-template / boilerplate |
| nnarduino-sketch | the sketch that is uploaded on the Arduino |
Please refer to the documentation for more infos.
