[Jasper’s] electronic load can not only act as ... [Jasper] also includes both the schematic and Arduino code, making it very easy to reproduce. There are tons of uses for a voltage controlled ...

That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed Control (ESC). [Fileark] built and ESC using an Arduino and has a couple of posts ...

Tinkercad also lets you paste the code for the Arduino and simulate the sketch to see whether your circuit works as intended.
