Whether a pin acts as input or output is determined with Pin.OUT or Pin.IN. You can read the GPIO level with pinname.value (). overflow guest house
ESP8266 ADC - Read Analog Values with Arduino
WebNov 9, 2024 · ADC Code Explained: At first, we import the ADC class from the machine module. The ADC class contains predefined functions to sample analog voltage and … Webfrom machine import ADC, Pin. import time. adc = ADC(Pin(26)) while True: print(adc.read_u16()) time.sleep(1) Turn the potentiometer to understand your maximum and minimum values. They need to be about between 0 and 65025. Now you can use this value to control the duty cycle for PWM on the LED. Change the code to the following. WebFeb 17, 2024 · from machine import ADC pot = ADC(0) To read the value from the ADC we use the read function. Try turning the potentiometer dial to different positions and enter adc.read () into the Thonny repl to get values. Make sure to call read at each of the potentiometers extremes. You will likely notice that you do not get a full 10 bit range of … overflowguard
