Again, I take zeros.

Someone??

Hello,

I use this code just to see if the current sensor works, but I get 0.0 on the serial! What am I doing wrong?

/*
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 and ground.

This example code is in the public domain.
*/

// the setup routine runs once when you press reset:
void setup()
{
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop()
{
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V):
float voltage = sensorValue * (1.0 / 1023.0);
// print out the value you read:
Serial.println(voltage);
}

Hello, now with the new code I get this error:

This report would have more information with

option enabled in File -> Preferences.

hello, where is the MySensor.h file??
