Quadcopter

In this project I have assembled a drone using ATMega328 as the main processing unit on both, receiving and transmitting ends. The drone has a MPU6050 integrated with it(for orientation and balancing), and HC-12 module as Transceiver.

General info

• Quadcopter RC (Transmitter)
  • Consists of an ATMega328 connected to a computer. This can be replaced by Raspberry PI for portability. RC sends the thrust values for each motor.
• Quadcopter flight controller (Receiver)
  • Consists of an ATMega328 connected to an IMU (MPU6050), 4 ESCs (which is connected to the brushless motors).
  • Quadcopter consists of two batteries, a 12V Li-Po Battery (for brushless motors)& a normal 9V (for the onboard flight controller).
    
  • There is an onboard OLED screen present for debugging & testing.
• Communication
  • Both sides communicate using HC-12 Transceiver module, at a baud rate of 38400.
