I tried controlling the display of flexible LED matrix with 3D gesture sensor.
ConfigurationDisplay the eye on the LED matrix and move with the 3D gesture sensor.
Flexible 8x8 RGB LED MatrixIt 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.

3D Gesture SensorFive electrodes are arranged in the up, down, left, right and middle. Gesture is sensed by changes in electrostatic capacitance of electrodes due to hand approach.
The Arduino library for the 3D Gesture Sensor is located in the following.
https://github.com/DFRobot/DFRobot_Gesture
This gesture sensor detects clockwise/counterclockwise rotation and movement directions (up, down, left, right) using program example "_3D_Gesture_Test.ino".
Please refer below for product details.

Arduino ProgrammingDisplay 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.
