SimpleLed

This Arduino IDE library is a simple way to control an RGB LED. It can also be used for other micro controllers that can be programmed via Arduino IDE.

Installation

Put this folder into your ~/Arduino/libraries folder.

Usage

Include the header file SimpleLed.h and initialize the module with three PWM pins of your micro controller (in the case of the Arduino Uno 3, 5 and 6 for instance). Don't forget to call begin() in the setup() method. Now you can use both methods setColor() and translateToColor() to control your LED.

The RGB Colors are specified with the Color type. Red, green and blue can have values between 0.0 (off) and 1.0 (completely on).

The following example defines three colors RED, GREEN and VIOLET and uses the two methods to control the led:

#include <SimpleLed.h>

const Color RED = {1.0, 0.0, 0.0};
const Color GREEN = {0.0, 1.0, 0.0};
const Color VIOLET = {1.0, 0.0, 1.0};

SimpleLed led(3, 5, 6);

void setup {
	led.begin();
}

void loop {
	led.setColor(RED);
	delay(1000);
	led.translate(GREEN, 3000);
	delay(1000);
	led.setColor(VIOLET);
	delay(1000);
	led.translate({1.0, 0.5, 0.0}, 3000);
}
