Hi guys,
I'm trying to activate phone caller, when I receive data from Arduino, via Bluetooth.
My idea was that received data be compared to desired word (or number) and if its true, phone caller starts.
I'm receiving successfully data that is displayed on label2.
But I can't figure out how to compare that data to desired one and start phone caller.
Here are my 2 attempts, but without success.
And button example code:
const int buttonPin = 2; // the number of the pushbutton pin
const int ledPin = 13; // the number of the LED pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
}
void loop(){
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == HIGH) {
// turn LED on:
digitalWrite(ledPin, HIGH);
Serial.println("call"); // send "call" to Android app. Also tried to send numbers.
}
else {
// turn LED off:
digitalWrite(ledPin, LOW);
}
}
Can someone give me some tip where I'm making mistake in these blocks?
THANK'S ALOT IN ADVANCE...
