Product Description

This is a brick component specially design for the Arduino board, you can light it up any color in the visible spectrum.

Using it with Arduino

It connects with four wires to the Arduino board.

The GND brick pin should be connected to the GND pin on the Arduino board and the IN1, IN2, IN3 pins to three different digital PWM pins on the Arduino.

By frequency variations on every PWM pin you can determine a color of your choice.

The source code is below :

int redPin = 5;
int greenPin = 9;
int bluePin = 6;

void setup()
{
  pinMode(redPin, OUTPUT);
  pinMode(greenPin, OUTPUT);
  pinMode(bluePin, OUTPUT);  
}

void loop()
{
  color(255, 0, 0);  
  delay(1000);
  color(0, 255, 0);  
  delay(1000);
  color(0, 0, 255); 
  delay(1000);
  color(255, 255, 0);  
  delay(1000);  
  color(80, 0, 80); 
  delay(1000);
  color(0, 255, 255);  
  delay(1000);
}

void color(int red, int green, int blue)
{
  analogWrite(redPin, red);
  analogWrite(greenPin, green);
  analogWrite(bluePin, blue);  
}

Using it with Raspberry PI

Connect the IN1, IN2, and IN3 led pins to any of the digital ports for the Raspberry PI board (marked yellow in the above picture). Connect the GND led pin to a Ground Raspberry PI port (marked black in the above picture) – or use a breaboard to get more ground ports.

Source code (Phyton) is below.

#!/usr/bin/env python
import time
import os
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)

GPIO.setup(4, GPIO.OUT)
GPIO.setup(17, GPIO.OUT)
GPIO.setup(21, GPIO.OUT)


while True:
        GPIO.output(4, True)
        time.sleep(0.5)
        GPIO.output(4, False)
        time.sleep(0.5)

        GPIO.output(17, True)
        time.sleep(0.5)
        GPIO.output(17, False)
        time.sleep(0.5)

        GPIO.output(21, True)
        time.sleep(0.5)
        GPIO.output(21, False)
        time.sleep(0.5)
