Guys！Color controllable lightning gadgets are always very expensive

Why not try to build your own? The cost is very low

So this is a DIY camera light that meets my specific needs and preferences

We can control the camera light via Bluetooth through an Android app, which is very easy and affordable

Display of required materials

Designing

Arrange the LED pixels in a 7 x 6 matrix and make sure each LED has a 100nF bypass capacitor.

Then place the microcontroller and its necessary crystal, USB data cable, battery holder, and Bluetooth connector into the design.

Assembling

Next, repeat the process for the bottom of the board but use a low temperature solder paste to keep the top components connected. Use a hot air soldering station to reflow the bottom of the board. Solder the Bluetooth module and make sure to set a custom Bluetooth name to identify the device.

Programming and Testing

Use the header to select whether to use the serial port for programming or Bluetooth communication. Put the jumper in the programming position, upload the code to the device using the USB cable, and put it in the Bluetooth position to activate Bluetooth communication.

Then use the Arduino IDE software to upload the code (attached at the end) and set up the device to receive serial data to continuously control the color and brightness of the pixels.

Housing

Use the prepared top and bottom parts (3D printed, attached at the end)

Use 3mm threaded inserts to assemble the device housing, and attach a white mat plexiglass screen to the top side of the gadget.

Android App

Create an Android app that uses a color palette and sliders to control the color and brightness of the camera light.

Finally, connect your phone to the camera light using Bluetooth and you're ready to go,

I'm sure it's awesome！
