这段代码用于读取连接在模拟引脚A0上的电位器(potentiometer)的电压值,并将其转换为实际的电压值后通过串行监视器打印出来。 /* ReadAnalogVoltage Reads an analog input on pin 0, converts it to voltage, and prints the result to the serial monitor. Attach the center pin of a potentiometer to pin A0...
voidloop(){// read the analog in value:sensorValue=analogRead(analogInPin);// map it to the range of the analog out:outputValue=map(sensorValue,0,1023,0,255);// change the analog out value:analogWrite(analogOutPin,outputValue);// print the results to the Serial Monitor:Serial.print("s...
https://www.arduino.cc/en/Tutorial/BuiltInExamples/AnalogReadSerial (2)模拟串口读 - Analog Read Serial This example shows you how to read analog input from the physical world using a potentiometer. Apotentiometeris a simple mechanical device that provides a varying amount of resistance when its ...
On the same lines you can read position of the stick anywhere in upper half hemisphere from combination of these values. Hookup So let's print the values on the terminal so that we can verify the working! Raw Sketch #define joyX A0 #define joyY A1 void setup() { Serial.begin(9600...
When I'm using configurePin and readVoltage for analog pins using an Arduino Leonardo board I'm getting the following errors in R2023B: "specified Key type does not exist" and "the first input must contain a multiple of 2 elements.." See code snippe...
