Arduino LED Lamp Flickering to Music




Introduction: Arduino LED Lamp Flickering to Music

I really wanted to create a lamp for my bedroom out of a large piece of drift wood that I collected. I found really cool through hole Neopixel LEDs on and I wanted to program them to blink to the beat of music.

Step 1: Items You Will Need

  • Arduino (and Arduino software on you computer)
  • driftwood
  • bread board
  • power source
  • audio cable
  • audio jack
  • speakers
  • 3 10k resistors
  • 220k resistor
  • 33pf capacitor
  • 2 100nf capacitors
  • 10nf capacitor
  • MSGEQ7
  • 3 N-channel MOSFET Transistors
  • wire
  • through hole led lights
  • headphone splitter
  • male to male jumper cables
  • drill to drill holes in drift wood
  • *depending how you set up your lamp, I used rope to hide my wires.

Step 2: The Circuit

You will need to do is create your circuit like the diagram shown above

Here is a link to the MSGEQ7 I looked at to understand the chip.

Step 3: The Coding

Step 4: Building the Lamp

Next I drilled holes in my drift wood where I wanted my LED lights to be and wired all the LEDs together. (Depending on you drift wood you may have a different layout of your LED lights).

You will need to create an in closer for your arduino and breadboard, I chose to place mine in a small side table. (again it all depends how you want yours displayed)

I also chose to place my speakers inside the table and line the table with rope, this is now necessary if you do not want this look.

    Cool idea! I'd love to see a video showing the LED effect with sound.

    Absolutely going to make this
