arduino code for my light up face mask
mask can be seen here https://twitter.com/TylerGlaiel/status/1265035386109128704
wiring: arduino nano, 9v battery, 9v to 5v regulator, flexible neopixel grid, electret mic breakout
9v battery to VIN and GND on the arduino
DIN on the led matrix to 330Ω resistor to digital pin 6 on the arduino
9v battery to 9v to 5v regulator, to 5v and GND on the led matrix
Electret mic to A7, 5V and GND on the arduino
guide for the LED matrix says that the power pins should be connected with a 1000uf capacitor, I left this out because I dont want a fat capacitor near my face. you probably shouldn't leave this out?
