<p>I have put a lot of work in to this. I hope that you give it al like. The manual is coming.</p> <h3>Print instructions</h3><h6># Desk lamp clock</h6> <p>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.</p> <p>The hole design is extremely simple so that it cannot go rong.<br/> All the parts need to be printed at 20% or higher, the ring need to be printed at 100%.</p> <h5>This is the code to set the time on the DS3231:</h5> <p>// DS3231_Serial_Easy<br/> // Copyright (C)2015 Rinky-Dink Electronics, Henning Karlsen.
