During the making there were several issues, first of all, there were problems in the code to run the rotary encoder that got fixed very quickly. Another issue to run the encoders were interrupt pins on the Arduino, which was fixed by using an Arduino Mega that has several interrupt channels. Later it turned out that the computer fans, that were bought for the prototype wouldn’t work. They turned on at a too high speed and didn’t go much higher, so they couldn’t reflect the speed from the wind and were barely able to blow any paper snippets. To solve that brushless DC motors together with ESC drivers are chosen and brought new issues. First, only one arrived and second, the power source for testing them doesn’t have a constant current which is responsible for only being able to use a higher rpm. One last big problem was that no one cooperated to 3D print the needed parts to be able to even use some functions. | During the making there were several issues, first of all, there were problems in the code to run the rotary encoder that got fixed very quickly.
