desk lamp clock

I have put a lot of work in to this. I hope that you give it al like. The manual is coming.

# Desk lamp clock

Everything need to be printed at 20%. This lamp is makes use from WS2812B led, I have used 60 of these. There is a matrix made of these led's. The matrix has a height of 5 led's and a width of 12 led's. and by using a DS3231 I am able to read the time and to print it on the matrix. The controller from the matrix is a arduino nano.

The hole design is extremely simple so that it cannot go rong.
All the parts need to be printed at 20% or higher, the ring need to be printed at 100%.

This is the code to set the time on the DS3231:

// A quick demo of how to use my DS3231-library to
// quickly send time and date information over a serial link
//
// To use the hardware I2C (TWI) interface of the Arduino you must connect
// the pins as follows:
//
// Arduino Uno/2009:
// ----------------------
// DS3231: SDA pin -> Arduino Analog 4 or the dedicated SDA pin
// SCL pin -> Arduino Analog 5 or the dedicated SCL pin
//
// Arduino Leonardo:
// ----------------------
// DS3231: SDA pin -> Arduino Digital 2 or the dedicated SDA pin
// SCL pin -> Arduino Digital 3 or the dedicated SCL pin
//
// Arduino Mega:
// ----------------------
// DS3231: SDA pin -> Arduino Digital 20 (SDA) or the dedicated SDA pin
// SCL pin -> Arduino Digital 21 (SCL) or the dedicated SCL pin
//
// Arduino Due:
// ----------------------
// DS3231: SDA pin -> Arduino Digital 20 (SDA) or the dedicated SDA1 (Digital 70) pin
// SCL pin -> Arduino Digital 21 (SCL) or the dedicated SCL1 (Digital 71) pin
//
// The internal pull-up resistors will be activated when using the
// hardware I2C interfaces.
//
// You can connect the DS3231 to any available pin but if you use any
// other than what is described above the library will fall back to
// a software-based, TWI-like protocol which will require exclusive access
// to the pins used, and you will also have to use appropriate, external
// pull-up resistors on the data and clock signals.
//

include <DS3231.h>

// Init the DS3231 using the hardware interface
DS3231 rtc(SDA, SCL);

void setup()
{
// Setup Serial connection
Serial.begin(115200);
// Uncomment the next line if you are using an Arduino Leonardo
//while (!Serial) {}

// Initialize the rtc object
rtc.begin();

// The following lines can be uncommented to set the date and time
//rtc.setDOW(WEDNESDAY); // Set Day-of-Week to SUNDAY
//rtc.setTime(12, 0, 0); // Set the time to 12:00:00 (24hr format)
//rtc.setDate(1, 1, 2014); // Set the date to January 1st, 2014
}

void loop()
{
// Send Day-of-Week
Serial.print(rtc.getDOWStr());
Serial.print(" ");

// Send date
Serial.print(rtc.getDateStr());
Serial.print(" -- ");

// Send time
Serial.println(rtc.getTimeStr());

// Wait one second before repeating :)
delay (1000);
}

For this code you have to download a driver, you are able to find it at the website that is in the code.

This is the main code, you upload this code after you did the first one.

// MATRIX DECLARATION:
// Parameter 1 = width of NeoPixel matrix
// Parameter 2 = height of matrix
// Parameter 3 = pin number (most are valid)
// Parameter 4 = matrix layout flags, add together as needed:
// NEO_MATRIX_TOP, NEO_MATRIX_BOTTOM, NEO_MATRIX_LEFT, NEO_MATRIX_RIGHT:
// Position of the FIRST LED in the matrix; pick two, e.g.
// NEO_MATRIX_TOP + NEO_MATRIX_LEFT for the top-left corner.
// NEO_MATRIX_ROWS, NEO_MATRIX_COLUMNS: LEDs are arranged in horizontal
// rows or in vertical columns, respectively; pick one or the other.
// NEO_MATRIX_PROGRESSIVE, NEO_MATRIX_ZIGZAG: all rows/columns proceed
// in the same order, or alternate lines reverse direction; pick one.
// See example below for these values in action.
// Parameter 5 = pixel type flags, add together as needed:
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs)
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers)
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products)
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2)

// Example for NeoPixel Shield. In this application we'd like to use it
// as a 5x8 tall matrix, with the USB port positioned at the top of the
// Arduino. When held that way, the first pixel is at the top right, and
// lines are arranged in columns, progressive order. The shield uses
// 800 KHz (v2) pixels that expect GRB color data.
