Neopixel rainbow VU meter

In this tutorial, I am going to show you how to build A beautiful VU meter using neopixel LEDs.its has 5 different animations, light intensity control and sensitivity control. super easy let's start 

what is VU meter

A volume unit (VU) meter or standard volume indicator (SVI) is a device displaying a representation of the signal level in audio equipment.

hardware needed

• Arduino (you can use any Arduino )
• neopixel led (no matter how many)
• audio socket
• 2*10k variable resistors(use the high quality to reduce noise)
• push button switch
• foam board(or MDF or plywood)

what is neopixel led

WS2812 LED strips are addressable and programmable Flexible LED strips which are very useful in creating the custom lighting effects. These LED Strips are powered by a 5050 RGB LED with a WS2812 LED driver inbuilt within it. Each LED consumes 60mA current and can be powered from a 5V DC supply. It has a single input data pin which can be fed from the digital pins of Microcontrollers. Depending on the intensity of the three individual Red, Green, and Blue LEDs we can create any colour we want

features of addressable LEDs

• 16.8 million colours per pixel
• Single-wire digital control
• Operating Voltage: 5V DC
• Current Requirement: 60mA per LED
• Flexible LED structure
• 5050 RGB LED with WS2812 driver

circuit diagram

connections

connect ground of led strip to ground 

connect 5volt of the led strip to 5volt of Arduino

data in pin to D6 and D5

connect the variable resistor to A0 and A1

left channel to A4 and right to A5

connect button to D4

making of the led tower

so I am using foam board to support the led stip you can use wood or MDF boards first I placed and fixed the neopixel on foam board then I cut and removed excess part.

then I also made a foam board base

and placed the led tower on top
