Instead of using the micro:bit's LEDs to make a sound level thingy, I used an Neopixel ring to display the sound level using it's LED's

Supplies

A micro:bit V2 (Must be V2!)

3x Male to Male jumper wires

Neopixel ring (the number of LEDs on your ring matters!)

A 5V power source (like a laptop or power bank that has USB for micro:bit)

Grab your neopixel ring, micro:bit, and your 3 male to male jumper wires! Connect the Neopixel's GND to the micro:bit's GND.

"set strip to..." block
