NeoLights: PC ambient lights manager for NeoJava

NeoLights demo

1 - Build

Use maven for build:

mvn package -DskipTests

2 - Arduino part

Here's the code you must load in the Arduino part of the UDOO

#include <Arduino.h>

#define TOP_STRIP 0x30
#define BOTTOM_STRIP 0x31

int led = 13;

int topRedPin = 10; //Red: PWM pin 10
int topGreenPin = 11; //Green: PWM pin 11
int topBluePin = 9; //Blue: PWM pin 9 
int bottomRedPin = 6; //Red: PWM pin 6
int bottomGreenPin = 7; //Green: PWM pin 7
int bottomBluePin = 5; //Blue: PWM pin 5 

void setup() { 

  // initialize serial communication at 115200 bits per second: 
  Serial.begin(115200); 
  
  // configure led's pin mode to output 
  pinMode(led, OUTPUT); 
  digitalWrite(led, HIGH); 
  setRGB(TOP_STRIP, 255, 0, 0);
  delay(100);
  setRGB(TOP_STRIP, 0, 255, 0);
  delay(100);
  setRGB(TOP_STRIP, 0, 0, 255);
  delay(100);
  setRGB(BOTTOM_STRIP, 0, 0, 255);
  delay(100);
  setRGB(BOTTOM_STRIP, 0, 255, 0);
  delay(100);
  setRGB(BOTTOM_STRIP, 255, 0, 0);
  delay(100);
  setRGB(TOP_STRIP, 255, 255, 255);
  setRGB(BOTTOM_STRIP, 255, 255, 255);
 
} 

void loop() { 
  
 if(Serial.available() >= 5){ 
   digitalWrite(led, HIGH); 
   int byteRead = Serial.read();
   if(byteRead == 0xff){
    int pos = Serial.read(); 
    int red = Serial.read(); 
    int green= Serial.read(); 
    int blue = Serial.read(); 
    setRGB(pos, red, green, blue);
   }
 }
 delay(10); 
 digitalWrite(led, LOW); 
}

void setRGB(int pos, int red, int green, int blue){
    if(pos == 0x30){ 
      analogWrite (topRedPin, red); 
      analogWrite (topGreenPin, green); 
      analogWrite (topBluePin, blue);
    } 
    else if(pos == 0x31){ 
      analogWrite (bottomRedPin, red); 
      analogWrite (bottomGreenPin, green); 
      analogWrite (bottomBluePin, blue); 
    } 
}

3 - Run

java -jar NeoLights.jar {HOST} {PORT}

HOST and PORT are those of the UDOO Neo which is running NeoJava ( https://github.com/BOSSoNe0013/NeoJava ) You can use screen software to keep app running in background
