2/7/2017These are defined in the appropriate // pins_*. c file. For the rest of the pins, we default // to digital output. void analogWrite(uint8_t pin, int val) { // We need to make sure the PWM output is enabled for those pins // that support it, as we turn it off when digitally reading or // writing with them.

Introduction to Arduino

The analogRead() reads the value from analog pin using analog-digital(AD) converter. The Arduino Uno has 6 10-bit AD converters. The analogRead() uses 4 registers named ADMUX, ADCSRA, ADCL and …

How to use AnalogRead function in Arduino with Examples

nalogRead()函数 @arduino. Reads the value from the specified analog pin. The Arduino board contains a 6 channel (8 channels on the Mini and Nano, 16 on the Mega), 10-bit analog to digital converter. 10-bit analog to digital converter. This means that it will map input voltages between 0 and 5 volts into integer values between 0 and

The function that you use to obtain the value of an analog signal is analogRead(pin). This function converts the value of the voltage on an analog input pin and returns a digital value from 0 to 1023, relative to the reference value. The reference is 5V on most Arduinos, 7V on the Arduino Mini and Nano, and 15V on Arduino Mega.
