#include <RCSwitch.h>

New to Arduino sketches that have #include

Downloaded and extracted files from:

Placed them in my “Sketchbook Location” folder (Arduino Uno R3)
Tried to open ReceiveDemo_Simple

/*
Simple example for receiving

*/

#include <RCSwitch.h>

RCSwitch mySwitch = RCSwitch();

void setup() {
Serial.begin(9600);
mySwitch.enableReceive(0); // Receiver on inerrupt 0 => that is pin #2
}

void loop() {
if (mySwitch.available()) {

int value = mySwitch.getReceivedValue();

if (value == 0) {
Serial.print(“Unknown encoding”);
} else {
Serial.print("Received “);
Serial.print( mySwitch.getReceivedValue() );
Serial.print(” / ");
Serial.print( mySwitch.getReceivedBitlength() );
Serial.print("bit ");
Serial.print("Protocol: ");
Serial.println( mySwitch.getReceivedProtocol() );
}

mySwitch.resetAvailable();
}
}

tried to compile and get the following error…

Help! please

YOU BEAUTY!

thanks so much!

I have the same problem. Can You tell what is solution?
