If he had met some scary fish, he would immediately return to the surface. PWM varies the amount of time a signal is HIGH or LOW. Its 90 degree position is generally referred to as 'neutral' position, because it can rotate equally in either direction from that point. As you can see, this math is not very friendly and would be tedious to do every time you wanted to set an angle, so in order to simplify that we're going to write a function in Python that does the math automatically then sets the angle. Although wed suggest the Buffalo Classic USB controller, the PS 3/4 and the Xbox 360/One controllers will work perfectly fine. 1) The HR204 is known for be touchy and tough to work accurately.
