but this sketch it works
const int analogInPin = A0; // Analog input pin that the potentiometer is attached to
const int ledPin = 13; // LED connected to digital pin 13
int sensorValue = 0; // value read from the sensor
void setup() {
// initialize serial communications at 9600 bps:
Serial.begin(9600);
pinMode(ledPin, OUTPUT); // sets the digital pin as output
}
void loop() {
// read the analog in value:
sensorValue = analogRead(analogInPin);
// determine alarm status
if (sensorValue >= 750)
{
digitalWrite(ledPin, HIGH); // sets the LED on
}
else
{
digitalWrite(ledPin, LOW); // sets the LED off
}
// print the results to the serial monitor:
Serial.print("sensor = " );
Serial.println(sensorValue);
// wait 10 milliseconds before the next loop
// for the analog-to-digital converter to settle
// after the last reading:
delay(10);
}
and I don't know to add 10 pin LED in this sketch. can you teach me ? my english is bad , sorry.
