Dear employer,
I have been working around arduinos and microcontrollers for last 6 years with certain projects involving motor controls. I have two specific questions regarding your project:
1. you want the functionality like each time when you power up the quadcopter, it shall finish exactly one sortie?
2. Any specific time for quadcopter to stay at 100m and any altitude sensors installed in it?
I shall be happy to finish the assignment for you.
