WebSep 2, 2024 · An analog to digital converter (or ADC) is a device that reads the voltage of an analog signal and converts it into a digital, or numeric, value. The microprocessor in your development board can’t deal with analog signals directly because they can be an infinite range of values. WebJan 5, 2024 · First you need to import a few modules to access the PWM output capabilities of CircuitPython: Download File Copy Code import board import pulseio Now you can create a PWM signal output that will drive the buzzer to make sound: Download File Copy Code buzzer = pulseio.PWMOut (board.D5, variable_frequency=True)
