arscripter

arscripter

A web-based approach to rapid Arduino prototyping. Program your Arduino board straight from the browser using JavaScript and GUI controls.

Requirements

• Arduino IDE
• Node.js
• PingFirmata

Installation

npm install -g arscripter

Usage

1. Connect Arduino via USB
2. Execute arscripter
3. Navigate to http://localhost:8080 in web browser

• Toggle the mode and/or value of a pin by clicking on the appropriate label
• PWM values can be set via the adjacent slider
• Analog values can be viewed in the adjacent graph

API

• loop(ms, handler())
  Execute the handler function every ms milliseconds

• display(msg)
  Print msg to the output pane

• getPinValue(pin)
  Returns the current value of the given pin

• setPinValue(pin, value)
  Write a value to a given pin

• toggleDigitalValue(pin)
  Write the opposite of the current value of a given pin

• getPinMode(pin)
  Returns the current mode of the given pin

• setPinMode(pin, mode)
  Set the mode of a given pin, one of the possible pin modes (see below)

Pin Modes

• 0: Input
• 1: Output
• 2: Analog
• 3: PWM

Basic Script

var pin = 13;
setPinMode(pin,1);

loop(1000, function() {  
  toggleDigitalValue(pin);

  setTimeout(function() {
  	display('Pin ' + pin + ' value: ' + getPinValue(pin) + '\n');
  }, 10);
  
});

Notes

• The first analog pin is reached at the number following the last digital pin (e.g. the last digital pin on the Uno is pin 13, so A0 is pin 14).
