Building Guide

Step 1: Making

We will use a 3D printed case to hold the entire assembly as well as to fix the acrylic sheet.

Take the case and the RGB LED strip.

Fix the RGB LED strip in the space given in the case.

Place Arduino Nano in the space given at the bottom of the case.

Make the connections and upload the Arduino code to Nano as given in the steps below.

To power up the nano add a battery to it.Add Battery

Step 2: Connection

Connect the Bluetooth Module and RGB LED Strip as given below:

Bluetooth:

  • 5V: 5v of Nano
  • GND: GND of Nano
  • Tx: Rx of Nano
  • Rx: Tx of Nano

RGB strip:

  • Vcc: D5 of Nano
  • Din: D6 of Nano
  • GND: GND of Nano

Battery:

  • Positive: Vin of Nano
  • Negative: GND of Nanoled_control

Step 3: Logic

Due to the transparency of the acrylic sheet, the light from the RGB strip will be scattered, thus giving it the holographic effect.

You can control the colors or patterns of the RGB strip using your Smartphone. How? Follow the steps below:

  • Install Dabble in your Smartphone.
  • Open the app.
  • Pair it with Nano.
  • Choose Gamepad module.

The following characteristics have been assigned to the different buttons of the Gamepad module.

  • Left Button: All the colors or pattern in this set follow the Color Wipe effect.
    • UP: Red
    • Down: Green
    • Left: Blue
    • Right: Rainbow
  • Right Buttons: All the colors or pattern in this set will follow theTheater Chase effect.
    • Triangle: Purple
    • Cross: Pink
    • Square: White
    • Circle: Rainbow

You can also try controlling the Brightness of the Strip by choosing the LED Brightness Control Module.

Step 4: Arduino Code

Upload the following Arduino Code to Nano:

Step 5: Conlusion

With this, your DIY Smartphone-controlled LED edge-lit acrylic sign is ready to light up your life!
