Glasses board with neopixel triple ring

Post by Plac95 »

Hi,
I would like to make the rezz glasses but with sound visualization. My question would be, if the board designed for the LED glasses front panel could work with the neopixel triple ring panels?
If not, which microphone would you recommend to use with the itsy bitsy m4?
Thanks!

The ItsyBitsy M4 is what is used in the guide with the triple ring NeoPixels.

Most of the guides use the MAX4466 / MAX9814 for CircuitPython / NeoPixel audio response.

Those are good analog mics. There is also a PDM option.

The mic to avoid with CircuitPython would be I2S. I2S in support is not there yet.

The Adafruit LED Glasses Driver - nRF52840 Sensor Board (https://www.adafruit.com/product/5217) cannot be used to drive neopixels because it does not have any pins available to drive the neopixels. The glasses are driven by an I2C interface.
