void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(A0);
float Value = sensorValue;
Serial.println(Value);
delay (500);
}
Inside serial monitor the values goes up 1-2-3-4…
It’s not make any sense!
If I disconnect the sensor the values always 0
what I want is to do is to detect ultrasonic waves, and show the data in scale on my PC, the second part easy, but what about the first one!
Is there any MAP I must use to convert these values to something readable!
