Build Motion Controlled Uncanny Eyes on TFT Displays with Teensy 4.1 + MPU6050 IMU

Описание: Build gyro controlled eyes—true motion controlled / movement controlled eyes—with an uncanny eyes setup powered by a Teensy 4.1 IMU. We integrate MPU6050 Teensy 4.1 using the MPU6050 (GY-521) over I2C IMU and drive 2 TFT displays. The project features round TFT display panels: 240x240 TFT GC9A01 and ST7789 (Teensy GC9A01, Teensy ST7789). Inspired by Adafruit uncanny eyes, this Teensy uncanny eyes build runs on Teensy 4.1 end-to-end. The eyes are responding to or mimicking the motion detected by the IMU - they move when the IMU moves.
