Direction_Control using KK flight controller & Arduino

The Tutorial Video :

In this video tutorial, I have used a

1.kk flight controller along with

2.An Arduino nano and

3.A GY-271 compass module (QMC5883l)

To add the feature of Direction Control using the initial direction as a reference and applying a proportional controller.

The first challenge was to accurately read the radio receiver's PWM signal for which I referred to

1.Joop Brokking's channel (the ultimate source to make drones using Arduino)channel: https://www.youtube.com/user/MacPuffdog

2. Electronoobs channel (Arduino drone playlist)Link: https://www.youtube.com/channel/UCjiV

I also used an extra channel(chn5) to toggle between normal mode, YAW_hold mode and Altitude Hold mode.

I hope this helps out others and better version for the same is developed in future.
