Iím trying to assemble a neopixel lightsaber with a nano biscotte v4.
When i tried a first raw test without altering the code in the board, the sound worked fine, but the neopixel strip didnt light up at all.
So i changed the code in the board to switch the ledstrip parameter to 288, the number of pixels in the 2 strips.
When i put the SD card back in the NBv4, i hear a periodic ę clic, clic Ľ and the activation switch doesnít do anything.
Any idea about what iím doing wrong?
Any help would be appreciated.
