Led Controlled By 3d Gesture Sensor

I tried controlling the display of flexible LED matrix with 3D gesture sensor.

Configuration

Display the eye on the LED matrix and move with the 3D gesture sensor.

Flexible 8x8 RGB LED Matrix

It has a 8x8 full color LED (NeoPixel) and soft by flexible board. The Arduino library for Neopixels is located in the following.

https://github.com/adafruit/Adafruit_NeoPixel

Please refer below for product details.

Arduino Programming

Display the eyeball on the LED matrix, move the eyes right and left with the left and right sensing of the gesture sensor, open and close the eyelids by vertical sensing. The pupil faces the front in clockwise or counterclockwise sensing.
