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