To read data from the serial monitor, first, you need to check whether user entered data or not. To check user data availability, you need to useSerial.available()function/command. When the user enters the data on the serial monitor, Arduino setsSerial.available()to return ‘1’ and in ...
// 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: Ser...
Voltage = (x * 5.0 )/ 1024.0;// this converts the analog value to corresponding voltage level Serial.print(“Level i = ” ) ; // these serial commands print value of i or level and voltage across wiper Serial.print(i) ; // and gnd on Serial monitor of arduino IDE Serial.print(“...
int sensorValue = analogRead(A0); // print out the value you read: Serial.println(sensorValue); delay(1); // delay in between reads for stability } (2)代码注释 AnalogReadSerial 串口模拟读取 Reads an analog input on pin 0, prints the result to the Serial Monitor. ...
ReadAnalogVoltage Reads an analog input on pin 0, converts it to voltage, and prints the result to the serial monitor. Graphical representation is available using serial plotter (Tools > Serial Plotter menu) Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V ...
Step 1: Read the Values From Memory You can then simply read the values again using a for loop Try this after you switched off the Arduino and on again. It will print your saved values to the Serial Monitor If you want, check out this thread ...

In this tutorial, I will be going through the steps on how to set up the Arduino serial monitor so you can debug and interact with a program running on the Arduino. This tutorial is pretty simple, but it can be a bit confusing at first especially if you’re new to programming and ...
