About this project

Many of you face a problem when it comes to Flight Controller which is the brain of the Multirotor. There are plenty of ready-made pre-flashed Flight controllers in the market for cheap, But have you thought of building your own Flight controller with your Arduino? So this is the right place to understand and build your own Flight controller for your Quadcopter or Multirotor with your Arduino.

Now the questions come, Where and how do I get the code for the quadcopter? So the answer is MultiWii.

MultiWii is a very popular flight controller software for DIY multi-rotors with a large community. It has support for various multi-copters with advanced features such as Bluetooth control via your smartphone, OLED display, barometer, magnetometer, GPS position hold and return to home, LED strips, and many more. So let’s build our flight controller using Arduino!

Step 1: Flight Controller Design

Here are the schematics for the flight controller board. You can make one on your general purpose PCB or can order a PCB from a manufacturer as I did.

ESC Connections

  • D3 << ESC 1 Signal Pin
  • D9 << ESC 3 Signal Pin
  • D10 << ESC 2 Signal Pin
  • D11 << ESC 4 Signal Pin

Bluetooth Module Connections

  • TX << RX
  • RX << TX

MPU-6050 Connections

  • A4 << SDA
  • A5 << SCL

LED Indicator

  • D8 << Anode Leg of LED

Receiver Connections

  • D2 << Throttle
  • D4 << Elerons
  • D5 << Ailerons
  • D6 << Rudder
  • D7 << AUX 1

Step 2: Building a Frame

Step 3: Attaching the Flight Controller Onto the Frame
