Usually I put my headphones on my desk but I have become tired of the mess with all the wires. I saw a video on youtube where there was one who had made a stand for his headphones … I’ll will go one step further …. I want to use an Arduino as a VU meter and light control.

more will come.

DeathStar Lamp

a55830

im using :

Lamp from IKEA IKEA PS 2014 is is the small one for now , but i hope to buy the big one and do the samr with that.
How it looks IKEA Lamp

WeMos D1

MotorShield / Stepmotor

20 NeoPixels

what i should end with is : customized deathstar IKEA

When im done ill post the code and a video and a link to all parts

UPDATE 30/1-17
WELL WELL
August 4 hmm ok, i just got some of the parts…
the stepper with spindel on is hard to track down… and is expensive (500dkk)
im not using WeMOS D1 (need to know more about it before i use it.)

Here is the new part list: (ill link to the items when im done)
arduino nano
some kind of motor controler
remotecontroll (IR)
10 NeoPixel strip (8x)
BlueTooth Controler for NeoPixel
stepper with spindel on

64×16 Led Matrix

RFiD Scanner

Jan 01, 2016
a55830

So i needed a RFiD scanner, well for about $5 you get RC522 breakoutboard.
The data i on the card/brick i needed was the SerialNumber.

The security system i need to use is kinda backwards so i needed to get key “0” from the card it returns 228 50 26 220 16 = E4 32 1A DC A1 in HEX
i only needed 4bit and in reverse DC 1A 32 E4 = 3692704484 in DEC
the first data can be used in the code to grant access if you mount a door magnet/servo.
The HEX just data
The 10DEC code you can use i pro systems.

as i said i needed a RFiD scanner just to get the 10DEC code.

In this build i use :

Arduino UNO, The finished build i used an Arduino Nano
