This example demonstrates I2S ADC capability to sample high frequency analog signals. The PWM signal generated with ledc is only for ease of use when first trying out. To sample the generated signal connect default pins 22(PWM) and 32(Sampling) together. If you do not wish to generate PWM ...

Use the pin 14 instead of pin 13. This pin is the A0 (Analog). But you have to refer it by 14 to use it as digital pin Change the circuit and sketch to use external pull-up on pin 13 or Remove the LED or the resitor connected to the LED from the Arduino Board....

ISR(ANALOG_COMP_vect) { counter++; } This is really simple, the instruction ISR() is a macro that tells the compiler that the following function is an Interrupt Service Routine. While ANALOG_COMP_vect is calledInterrupt Vectorand it tells the compiler which interrupt is associated to that ro...
