The arduino UNO ist located in the middle of the multicopter. The orientation is shown in the image. The usb port is the backside of the drone. It has a connection to the remote sensor and reads in the pwm control signals from the remote control. Via I2C a MPU6050 is connected and can provide gyro and accelerometer data. The power supply is done via a power separation board to spread the power supply to every engine.
- Power Supply
The power is provided via a 11.7V 3 Cell LIPO accumulator The voltage is send to the esc and is converted to 5V to provide power to the arduino and the remote receiver.
- ESC Signal Connection
The connection of the esc cables to the sensor board is shown in the next image:
| Front Right | Rear Right | Rear Left | Front Left |
|---|---|---|---|
| GPIO 4 | GPIO 5 | GPIO 6 | GPIO 7 |
| CCW ⭯ | CW ⭮ | CCW ⭯ | CW ⭮ |
- Remote Signal Connection The signal of the remote receiver are processed via interrupt handling on the arduino, this is why i need to attach the ports to specific pins on the UNO. Because of a broken pin at GPIO8 it was not possible to use the same sketch as YMFC, so i need to shift the GPIO Interrupts by one. By this i was not able to use the remote LED on GPIO 12.
