This drone was a direct upgrade to the previous model that I built. Version 1 was made using an Arduino Uno board at the core. This was a quick build designed to get something into the air for the first time. The body was a rough design and had a lot of flaws that made it harder to work with. These were dealt with in the next iteration of the drone.
The main upgrade for version 2 was a redesign of the drone body. My friend got a DJI mini drone with foldable arms for storage and I wanted to try the same thing with this project. I replaced the fixed arms with arms that all swiveled into the body. Secondly, I created a complete bottom half of the drone so that the battery was no longer exposed. There were a handful of small electronics adjustments as well. In order to save space on the inside, I swapped out the Arduino Uno for an Arduino Nano to save space. I also added a power switch onto the outside of the drone to make turning the motors on and off easier and safer. Finally, I added a magnetic cover to the drone so that I could easily remove the top case to access electronics.
