Hello i am trying to get values from a sensor with sound and i get from the digital pin 2 everytime 1. and from the A0 something like 27. Can anyone help me out?
int DO = 2; //Pin for Digital Output - DO
int DA = A0; // Pin for Analog Output - AO
int threshold = 532; //Set minimum threshold for LED lit
int sensorvalue = 0;
void setup() {
Serial.begin(9600);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
pinMode(8, OUTPUT);
pinMode(9, OUTPUT);
}
void loop() {
Serial.print("Digital: ");
Serial.println(digitalRead(DO)); //Print the digital value
if (sensorvalue >= threshold) { //Compare analog value with threshold
digitalWrite(3, HIGH);
digitalWrite(4, HIGH);
digitalWrite(5, HIGH);
digitalWrite(6, HIGH);
digitalWrite(7, HIGH);
digitalWrite(8, HIGH);
digitalWrite(9, HIGH);
}
else {
digitalWrite(3, LOW);
digitalWrite(4, LOW);
digitalWrite(5, LOW);
digitalWrite(6, LOW);
digitalWrite(7, LOW);
digitalWrite(8, LOW);
digitalWrite(9, LOW);
}
}
