An Arduino library that can programmatically manipulate the LED color changing light strips controlled by a 44 Key IR Remote.

In the Arduino IDE, click Sketch >> Include Library >> Manage Libraries...

With the Arduino Library Manger window open, in the Filter your search... input type: FlashlightLED.

Select the FlashlightLED library and click Install.

Include the FlashlightLED library in your Arduino sketch.

#include <FlashlightLED.h>

Notes:

• Requires one infrared (IR) LED.
• The IR LED short leg is ground.
• Pin #3 MUST be used as the transmit pin. This library uses the Arduino IRremote library by Sherriff, which uses pin #3.
• The resistor value in the image is 100ohm, but higher resistor values may be used to shorten the distance of the transmission when interference is an issue.
• This library transmits on the IR NEC Protocol. NEC Protocol Tutorial

Notes:

• All methods in the library are capitalized e.g. QUICK, DIY3, SLOW, COLOR, RANDOM_COLOR etc...
• Any button with a printed word has a matched method i.e. the button with the word FLASH maps to the method FlashlightLED.FLASH().
• Any button with numbers displays the two arguments required to activate the corresponding button via the method displayed in the attached word bubble: method(column, row).

The following methods change the luminosity of the lights.

Notes:

• The IR Remote has eight luminosity settings. It takes seven clicks to get from full dim to full brightness or vice versa.
• Both the BRIGHTEN and DIM method default to 10 pulses to over compensate in case of a missed signal.

/*
Takes an optional integer parameter.
If no integer is provided ten pulses will be emitted.
When an integer is provided, the integer will be the number of pulses.
*/

BRIGHTEN(int:optional)

DIM(int:optional)

The following method was added to attempt a specific luminosity.

Notes:

• The library cannot keep track of the current luminosity setting as there is no confirmation signal from the LED lights.
• The LUMENS method attempts full dim, then applies the default or supplied argument.
• If a level of six out of eight settings is desired, the method will first apply ten dimming pulses, then use the supplied 5 integer to count up from a dim setting of 1.

/*
Takes an optional integer parameter.
If no integer is provided four pulses will be emitted to achieve a middle luminosity.
When an integer is provided, the integer will be the number of pulses starting at full dim.
*/

LUMENS(int:optional)

The following methods change the speed of flashing lights.

Notes:

• The IR Remote has sixty luminosity settings. It takes sixty clicks to get from the longest to the shortest flash interval or vice versa.
• Both the QUICK and SLOW method default to 65 pulses to over compensate in case of a missed signal.

/*
Takes an optional integer parameter.
If no integer is provided 65 pulses will be emitted.
When an integer is provided, the integer will be the number of pulses.
*/

QUICK(int:optional)

SLOW(int;optional)

The following method was added to attempt a specific flash interval.

Notes:

• The library cannot keep track of the current flash interval setting as there is no confirmation signal from the LED lights.
• The SPEED method attempts to set the longest flash interval, then applies the default or supplied argument.
• If a level of thirty out of sixty settings is desired, the method will first apply 65 dimming pulses, then use the supplied 30 integer to count up from a slow setting of 1.

/*
Takes an optional integer parameter.
If no integer is provided thirty pulses will be emitted to achieve a middle flash interval.
When an integer is provided, the integer will be the number of pulses starting at the longest interval setting.
*/

SPEED(int:optional)

The following method is used to select one of the twenty selectable colors.

Notes:

• The IR Remote has twenty default colors to choose from.
• The COLOR method sends one pulse.
• There are four columns and five rows.

/*
Takes two required integer parameters: column #, row #.
*/

COLOR(int:required, int:required)

/*
Takes one optional integer parameter: column #.
If an integer:column is supplied, the random selection will be confined to that column.
If no integer is provided, a random color will be selected from any column and row with each method call.
*/

RANDOM_COLOR(int:optional)

The following method is used to select a color arrow.

Notes:

• The IR Remote has six color arrows to choose from.
• The ARROW method sends one unless the third optional argument is supplied.

/*
Takes two required integer parameters: column #, row #.
*/

ARROW(int:required, int:required)

The following methods map to the DIY# buttons.

Notes:

• The IR Remote has six memory selections.

DIY1()

DIY2()

DIY3()

DIY4()

DIY5()

DIY6()

PLAY()

POWER()

JUMP3()

JUMP7()

FADE3()

FADE7()

FLASH()

AUTO()

Notes:

• All methods can be chained.
• A DELAY method is available to separate method chaining with delays.

DELAY(int:required)

Potential fire hazard!

When the lights are coiled and powered on, enough heat is produced to melt the lights and reel. When under power uncoil lights to prevent high heat condition.

Example sketch sends an IR signal equivalent of the AUTO button on the remote and then sends an IR signal equivalent to the <increase brightness symbol> button on the remote. The LED light strips should enter into AUTO mode and set FULL brightness.

#include <FlashlightLED.h> // Import library;

FlashlightLED lights; // Now referenced as lights throughout sketch.

void setup(){
  // Serial Monitor @ 9600 baud
  Serial.begin(9600);
  lights.AUTO().BRIGHTEN();
  lights.COLOR(0,3).DELAY(5000).COLOR(0,0).DELAY(10000).FLASH();
}

void loop(){}
