Hacking a Fairphone

Today I had the time to place "some" LEDs.. :D

#include <Adafruit_NeoPixel.h>

int LEDs[8]{ 8,9,10,11,12,13,14,15 };

// Pin connected to the Neopixel 
#define PIN            17

// How many NeoPixels are attached 
#define NUMPIXELS      1

// Definition of the Neopixel
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
// Setting the pinmode of the GPIOs for the LEDs
	for (int i = 0; i < 8; i++) {
		pinMode(LEDs[i], OUTPUT);
}
// Starting the Neopixel
	pixels.begin();
	pinMode(17, OUTPUT);
}
void loop() {

// LEDs are blinking in a row 
	for (int i = 0; i < 8; i++) {
		digitalWrite(LEDs[i], HIGH);
		if (i > 0) {
			digitalWrite(LEDs[i - 1], LOW);
		}
		delay(50);
    }
	for (int i = 8; i >= 0; i--) {
		digitalWrite(LEDs[i], HIGH);
		digitalWrite(LEDs[i + 1], LOW);
		delay(50);
	}
	for (int i = 0; i<256; i++) {		
		// pixels.Color takes RGB values, from 0,0,0 up to 255,255,255
		pixels.setPixelColor(0, pixels.Color(0, i, 0)); // Moderately bright green color.
		pixels.show(); // This sends the updated pixel color to the hardware.
		delay(5); // Delay for a period of time (in milliseconds).
	}
	for (int i = 255; i>0; i--) {	
		// pixels.Color takes RGB values, from 0,0,0 up to 255,255,255
		pixels.setPixelColor(0, pixels.Color(0, i, 0)); // Moderately bright green color.
		pixels.show(); // This sends the updated pixel color to the hardware.
		delay(5); // Delay for a period of time (in milliseconds).
	}
	pixels.setPixelColor(0, pixels.Color(0, 0, 0)); // Neopixel: off
	pixels.show(); // This sends the updated pixel color to the hardware.
}

This makes programming a lot easier!! :)

I sold all other pcbs of the cap. buttons and now one is still here :) 

Any Fairphoners out there who want one :) 

I also can solder everything up for you if you want that :) 

Text me if there's interest !!! :) 

Edit: sold !! 

I designed and ordered a new PCB for the Fairphone 2. 

It`s much like those prototyping-shields you have for your Arduino. And the purpose is to start tinkering and building things in combination with the PF2. This can not only extand your possiblities you have with your phone but also gives you the full control of the additional hardware you want.

Feel free to ask whatever is on your mind :)

I'm trying to blog frequently :)
