Analog Read Serial - Arduino Docs
2024年10月2日 · Read a potentiometer, print its state out to the Arduino Serial Monitor. This example shows you how to read analog input from the physical world using a potentiometer. A potentiometer is a simple mechanical device that provides a varying amount of resistance when its shaft is turned.
analogRead() - Arduino Docs
See the table below for the usable pins, operating voltage and maximum resolution for some Arduino boards. The input range can be changed using analogReference (), while the resolution can be changed (only for Zero, Due and MKR boards) using analogReadResolution ().
Analog Read Serial - Arduino Project Hub
2020年6月7日 · This example demonstrates how to read analog input from a potentiometer. The analog input is read and the result is printed in the Serial Monitor. When the shaft is turned all the way in one direction, there are 0 volts going to the pin, and the input value is 0.
Read Analog Voltage - Arduino
2024年10月2日 · This example shows you how to read an analog input on analog pin 0, convert the values from analogRead() into voltage, and print it out to the serial monitor of the Arduino Software (IDE). Hardware Required
Analog In, Out Serial - Arduino
2024年10月2日 · This example shows you how to read an analog input pin, map the result to a range from 0 to 255, use that result to set the pulse width modulation (PWM) of an output pin to dim or brighten an LED and print the values on the serial monitor of the Arduino Software (IDE).
analogRead () - Arduino Reference
2024年11月8日 · Reads the value from the specified analog pin. Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage(5V or 3.3V) into integer values between 0 and 1023.
