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 adafruit.com 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)
- bread board
- power source
- audio cable
- audio jack
- 3 10k resistors
- 220k resistor
- 33pf capacitor
- 2 100nf capacitors
- 10nf capacitor
- 3 N-channel MOSFET Transistors
- 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.
