Universal Led is an USB device based on an Arduino nano (clone) to easily control 5 leds on Windows
Demo: https://www.youtube.com/watch?v=hgvi46x4oaE

You can choose 6 color for each leds. (White/Red/Green/Blue/Yellow/Orange/Purple)

• Install drivers for arduino nano (clone ch340g) : http://nano.madnerd.org
• Download arduino/python code : http://uled.madnerd.org
• Upload sketch uled.ino
• Download application : http://uledapp.madnerd.org

How to install drivers : https://www.youtube.com/watch?v=m3CsftsfiQU

• Arduino nano CH340G: 2€
• 30 leds WS2812B : 4.50€ ( 5 leds :0.75€)
• Resistor pack 400pcs (3€) (1 resistor: 0.0071€)
• Total : 9.5€ (2.75€)

Wiring / How to make it: https://www.youtube.com/watch?v=hgvi46x4oaE

Do not used more than 5 leds without a dedicated power supply or this can damage the leds
Each led can draw up to 60ma at full brightness
An Arduino can provided up to 500ma (on 5v/Gnd pin)
5 leds = 5x60ma = 300ma

• D6 --> RESISTOR (470Ohm) DI
• +5V --> 5V
• GND --> GND

This model is an all purpose case for arduino nano projects

You will need to fill a hole for the led strip (see wiring instructions)

• Check out: http://github.com/pigetArduino/utest
• The source code is available in apps/utest

You can test the device in Arduino Serial Monitor
Baudrate : 115200 / No Line Ending

• ULed --------> Check if device is correct (turn off all led)
• X:Y -------> (Where X is the led and Y the color)
• 1:3 -------> (led 1 Green)

• 0 : OFF
• 1 : White/ON
• 2 : Red
• 3 : Green
• 4 : Blue
• 5 : Yellow
• 6 : Orange
• 7 : Purple
