Make a sound sensitive NeoPixel cap with this Adafruit VU Meter Baseball Hat tutorial

Add sound-reactive NeoPixels to your baseball cap! Use our 144-density NeoPixel strip as a wraparound VU meter with a small microphone at the side. The FLORA microcontroller takes input from the mic and sends the LEDs flashing according to the volume in the room!

This intermediate level wearables project requires some precision soldering and sewing. We recommend checking out the following guides before you begin:
• Getting Started with FLORA
• Adafruit Guide To Excellent Soldering
• Adafruit NeoPixel Überguide

You’ll have installed the Adafruit Arduino software by now, OR you can program your FLORA directly from your browser using Codebender. Fancy!

For this project you’ll need:
• FLORA main board
• Electret Microphone Amplifier
• 144-density NeoPixel strip
• 500mAh lipoly battery and charger
• alligator clips
• soldering iron and solder
• wire strippers, pliers, and flush diagonal cutters
• (optional but very helpful) third hand tool
• stranded wire (ribbon cable works great too)
• sewing needle and thread
• scissors
• sewing pins or masking tape
• sturdy tape like gaff or packing
• baseball cap (we recommend getting one size up to save room for the battery)
