im trying to use a func inside Loop in Arduino. It wont work;
Params are numeroPin, sonido and delay. I tried everything but it seems like im not able to fix this
void setup() {
for(int i = 2 ; i<=9; i++){
pinMode(i, OUTPUT);
}
}
int C4 = 262; // LED 4
int D4 = 294; // LED 5
int E4 = 330; // LED 6
int F4 = 349; // LED 7
int G4 = 392; // LED 8
int C5 = 523; // LED 9
void sonar(numeroPin, sonido, delay) {
tone(2, sonido);
digitalWrite(numeroPin, HIGH);
delay(delay);
digitalWrite(numeroPin, LOW);
}
void loop() {
sonar(4, C4, 1000);
sonar(5, D4, 1000);
sonar(6, F4, 167);
sonar(7, E4, 167);
sonar(5, D4, 167);
sonar(8, C5, 1000);
sonar(9, G4, 500);
}
I tried it and it fails to compile.

Answer 1

declare parameters type in your function :
void sonar(int numeroPin, int sonido, int mydelay)
and avoid 'delay' as variable name as it is system reserved.
void setup() {
for (int i = 2 ; i <= 9; i++) {
pinMode(i, OUTPUT);
}
}
int C4 = 262; // LED 4
int D4 = 294; // LED 5
int E4 = 330; // LED 6
int F4 = 349; // LED 7
int G4 = 392; // LED 8
int C5 = 523; // LED 9
void sonar(int numeroPin, int sonido, int mydelay) {
tone(2, sonido);
digitalWrite(numeroPin, HIGH);
delay(mydelay);
digitalWrite(numeroPin, LOW);
}
void loop() {
sonar(4, C4, 1000);
sonar(5, D4, 1000);
sonar(6, F4, 167);
sonar(7, E4, 167);
sonar(5, D4, 167);
sonar(8, C5, 1000);
sonar(9, G4, 500);
}
