==Usage==
 +
 +
===Basic Functionality===
 +
The ColorLED is a trinket which emits different colors based on the set red, green, and blue values. A Core module can control the ColorLED to output the desired colors.
 +
 +
Note: ColorLEDs can be connected together in a daisy chain fashion, and each ColorLED can be addressed individually using the index number. First ColorLED being 0, second ColorLED being 1, etc.
 +
===Programming===
 +
<tab name="Arduino for Microduino" style="width:100%;">
 +
==Introduction==
 +
The ColorLED is used as an output pin. The library is based on the Adafruit_NeoPixel library '''([https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library Read more])''' is used to control the ColorLED. Most of the functions are similar.
 +
==Key Functions==
 +
*Required Libraries: '''Microduino_ColorLED.h'''
 +
*Key Functions:
 +
** Constructor: '''ColorLED strip = ColorLED(num_colorleds, colorled_pin)''' - creates the ColorLED object
 +
***'''num_colorleds''' - defines the number of ColorLEDs connected to the '''colorled_pin'''
 +
***'''colorled_pin''' - defines the pin the ColorLEDs is connected to
 +
** '''strip.begin()''' - initializes the ColorLED object
 +
** '''strip.setPixelColor(colorled_index, red_value, green_value, blue_value)''' - configures the color value for that colorled index, must call '''strip.show()''' for the ColorLED to actually display the change
 +
***'''colorled_index''' - is the index of the ColorLED to configure, first in the chain is 0, second is 1, etc
 +
***'''red_value''' - red value to set, between 0 (off) and 255 (maximum on)
 +
***'''green_value''' - green value to set, between 0 (off) and 255 (maximum on)
 +
***'''blue_value''' - blue value to set, between 0 (off) and 255 (maximum on)
 +
** '''strip.show()''' - call this function after setting the color values for the ColorLED to actually display the color
 +
 +
==Example==
 +
This is a simple example which:
 +
*Turns the ColorLED to red
 +
*Waits 1 second.
 +
*Turns the ColorLED to green
 +
*Wait 1 second.

*Turns the ColorLED to blue

Usage

Basic Functionality

The ColorLED is a trinket which emits different colors based on the set red, green, and blue values. A Core module can control the ColorLED to output the desired colors.

Note: ColorLEDs can be connected together in a daisy chain fashion, and each ColorLED can be addressed individually using the index number. First ColorLED being 0, second ColorLED being 1, etc.

Programming

Introduction

The ColorLED is used as an output pin. The library is based on the Adafruit_NeoPixel library (Read more) is used to control the ColorLED. Most of the functions are similar.

Key Functions

  • Required Libraries: Microduino_ColorLED.h
  • Key Functions:
    • Constructor: ColorLED strip = ColorLED(num_colorleds, colorled_pin) - creates the ColorLED object
      • num_colorleds - defines the number of ColorLEDs connected to the colorled_pin
      • colorled_pin - defines the pin the ColorLEDs is connected to
    • strip.begin() - initializes the ColorLED object
    • strip.setPixelColor(colorled_index, red_value, green_value, blue_value) - configures the color value for that colorled index, must call strip.show() for the ColorLED to actually display the change
      • colorled_index - is the index of the ColorLED to configure, first in the chain is 0, second is 1, etc
      • red_value - red value to set, between 0 (off) and 255 (maximum on)
      • green_value - green value to set, between 0 (off) and 255 (maximum on)
      • blue_value - blue value to set, between 0 (off) and 255 (maximum on)
    • strip.show() - call this function after setting the color values for the ColorLED to actually display the color

Example

This is a simple example which:

  • Turns the ColorLED to red
  • Waits 1 second.
  • Turns the ColorLED to green
  • Wait 1 second.
  • Turns the ColorLED to blue
  • Waits 1 second.

Note: Important lines of code are highlighted. 

//Include the required libraries to control the ColorLED
//Based on: https://learn.adafruit.com/adafruit-neopixel-uberguide/arduino-library
#include <Microduino_ColorLED.h>

//Define the pin the ColorLED is connected to
const int COLORLED_PIN = 6;

//Define the number of ColorLEDs daisy chained together
const int COLORLED_NUM = 1;

//Declare and initialize the ColorLED object
ColorLED strip = ColorLED(COLORLED_NUM, COLORLED_PIN);

void setup() {
  // put your setup code here, to run once:

  //Initial serial communication port at 9600 baud
  Serial.begin(9600);

  //Initialize the ColorLED class object
  strip.begin();

  //Initialize all ColorLEDs to 'off'
  strip.show();
}

void loop() {
  // put your main code here, to run repeatedly:

  //Configure the first ColorLED to maximum red
  strip.setPixelColor(0, 255, 0, 0);
  //Set the ColorLED
  strip.show();

  //wait 1 second
  delay(1000);

  //Configure the first ColorLED to maximum green
  strip.setPixelColor(0, 0, 255, 0);
  //Set the ColorLED
  strip.show();

  //wait 1 second
  delay(1000);

  //Configure the first ColorLED to maximum blue
  strip.setPixelColor(0, 0, 0, 255);
  //Set the ColorLED
  strip.show();

  //wait 1 second
  delay(1000);
}
