Ambilight for any pc monitor tutorial (prismatik, arduino nano, ws2812b)

The housing with lid is part of the Ambilight Monitor project. The case was printed with PLA. The following components are also required for the Ambilight:

• Arduino Nano
• Power supply 5V 2A
• ws2812b 88 LEDs (32 Top, 19 Left, 19 Right, 18 Bottom)
• 3x Terminals for wirre connecting
• Mini USB cable
• 1x Mosfet IRFZ44N

The following program must be installed on the Arduino: https://github.com/dmadison/Adalight-FastLED
The number of LEDs must be set to 88 in the program.

Then install the Prismatic software (several downlods possible, use the latest version!): Https://lightpack.tv/pages/downloads 

Select “Run configuration wizard” under Device and execute it. Use the COM port as with the Arduino program installlation (attention, the COM port can change if a different USB port is used). Select the LED arrangement as on the screen.

In the code program, I added that pin D4 is initialized and set to HIGH at the beginning. So that the transistor switches through. The transistor is used to switch off the LEDs when the PC shuts down and thus the Arduino switches itself off. Otherwise the LEDs would still have power and would continue to light up.

The code is (put in setup section):

pinMode(4,OUTPUT);
digitalWrite(4,HIGH);
