Hi, I have entered the sketch from the Arduino projects book – Love_O_Meter. When I try to verify I get an error relating to line 5 of the sketch that says;
‘pinNumber’ was not declared in this scope
const int sensorPin = A0;
const float baselineTemp = 20.0;
void setup() {
Serial.begin(9600); // open a serial port
for(int pinNnumber = 2; pinNumber<5; pinNumber++){
pinMode(pinNumber, OUTPUT);
digitalWrite(pinNumber, LOW);
}
}
void loop() {
int sensorVal = analogRead(sensorPin); //
Serial.print("Sensor Value: ");
Serial.print(sensorVal);
//convert the ADC reading to voltage
float voltage = (sensorVal/1024.0) * 5.0;
Serial.print(", Volts: ");
Serial.print(voltage);
Serial.print(", degrees C: ");
// convert the voltage to temperature in degrees
float temperature = (voltage - .5) * 100;
Serial.println(temperature);
if(temperature < baselineTemp+2){
digitalWrite(2, LOW);
digitalWrite(3, LOW);
digitalWrite(4, LOW);
}else if(temperature >= baselineTemp+2 &&
temperature < baselineTemp+4){
digitalWrite(2, HIGH);
digitalWrite(3, LOW);
digitalWrite(4, LOW);
}else if(temperature >= baselineTemp+4 &&
temperature < baselineTemp+6){
digitalWrite(2, HIGH);
digitalWrite(3, HIGH);
digitalWrite(4, LOW);
}else if(temperature >= baselineTemp+6){
temperature < baselineTemp+4){
digitalWrite(2, HIGH);
digitalWrite(3, HIGH);
digitalWrite(4, HIGH);
}
delay(1);
}
‘pinNumber’ was not declared in this scope
Can someone help me understand why this error comes up? I believe I have entered everything as shown in the book.
There is a similar topic at the Arduino forum, but it doesn't help me out either.
Thanks in advance!
