1. PWM Introduction1. PWM definition: Pulse Width Modulation (PWM) is a digital signal that is most commonly used to control circuits. The signal is set to high (5v or 3.3v) and low (0v) in a predefin...
Speaking of level conversion, when writing programs, we actually need an oscilloscope to observe the phenomenon, which means that we pay the tuition for 211 universities, but we are not attending a 21...
