An Arduino, IMU, two servos, and a battery pack detect deceleration and automatically increase the spoiler angle just like the big boys, but without needing any integration into the vehicles systems.
Even if you have a small hand! The drone is based around an Arduino Pro Mini, and uses an MPU6050 IMU for motion sensing and flight control. Communication with the drone is via an NRF24L01.
It can function as a remote control, a Bluetooth gamepad, or even a smart automation device—all tailored to individual needs.
