DIY RGB Tube light is a multi functional tube light which can be used in photography, light painting photography, film making, gaming, as a VU meter and more. The tube light can be controlled by Prismatik software or by a push button. These tub lights are made using a Arduino Nano and WS2812B LED strip.

Step 1: Supplies:

  1. (1) Arduino Nano :
  2. (2mt) WS2812B LED Strip:
  3. (2) White Tube Lights Or Aluminum Light Fittings with Diffuser : Or
  4. (1) 5V 5A Power Supply :
  5. (1) Push Button :
  6. (1) Wires :
  7. (1) DC Connector :

Step 2: Tube Lights Disassembling:

  • Disassemble the tube light by removing end caps, separating diffuser and removing whites LED strip from the tube.

Step 3: Circuit Connection:

  • Make all the connections as shown in circuit diagram.

Step 4: Assembling:

  • Put all the electronics in the tube, put back the end caps and seal the diffuser using clear tape.

Step 5: Tube Light 2:

  • Similarly make the second tube but this time use only WS2812b LED strip, connector, wires and connect the tube lights.

Step 6: Code for Software:

  • Download the given zip files and extract them.
  • RGB_Tube_code & software zip
  • Open the RGB Tube code & software file, open the code given in Arduino IDE.

  • Install the FastLED library in Arduino IDE.

  • You can enter the number of LEDs you used in your tube lights, I used 65 LEDs in each tube lights, i.e. 130 LEDs in both tube lights.

  • #define NUM_LEDS 130
  • Remember the port number. (for example: com8)

  • Connect the Arduino to your PC, select the board type, select the port and upload the code.

Step 7: Software Setup:

  • Install the prismatik software in your PC.
  • Open the software and click on device.
  • Click on Run configuration wizard and simply click on Next -> Next.
  • Enter the Serial Port number and click Next -> Next
  • Enter the number of LEDs at sides (i.e. in my case top=0, side=65, bottom=0) and click on custom -> Next.
  • Adjust the sliders to get white color on the tube lights and click on finish.
  • Now you can choose different mode in the software and display on tube lights.

NOTE: The Arduino should be connected to the PC.

Step 8: Button Code:

  • Open the Button_Tube code in Arduino IDE.
  • With this code you can change the color of the Tube Lights with the push of button.
  • Install the Pushbutton library by clicking on sketch ->Include library -> Add zip library and select the Pushbutton-2.0 zip file in Button_Tube file.
  • Enter the number of LEDs.
  • #define NUM_LEDS    130
  • In this code you can enter the values of the colors at CRGB(----, -----, -----);

  • for(int i = 0; i < NUM_LEDS; i++){      <br>
    leds[i] = CRGB(0, 100,255);;
  • You can copy paste the color values from color picker.

  • Connect the Arduino to your PC, select the board type, select the port and upload the code.

Step 9: NOTE:

  • You can make this lights portable by using a power bank or some batteries.
  • By using any Wi-Fi board like ESP8266 or ESP32 you can change the colors of the tube lights with a mobile app.
