Electronics Configuration
Figure 1. Electronics Attached to Drone
The Elegoo Uno R3 board is programmed to function as the flight controller, with the MPU 6050 sensor connected directly to the board. To simplify the setup, all four Electronic Speed Controllers (ESCs) and the LiPo battery connection are soldered to the Power Distribution Board (PDB). Power is drawn from the PDB to power the boards.
The ESCs, which control the motor speed and power transfer, are connected directly to the motors. The speed of each motor is determined by the signal wires from the respective ESCs connected to the Arduino board. The motor's rotational direction is determined by the connection to the ESCs; to reverse the direction of rotation, simply flip any two connections to change the motor phase.
