Auduino lesson1: LCD and bluetooth exercise

Auduino lesson1:Use my cell phone(Android) Control the LCD display via bluetooth. Source code as below: the variable parameter ‘serialreceive’ is very impotant, if you directly use Serial.read(), it will be error.
#include <LiquidCrystal.h>

LiquidCrystal lcd(12,11,2,3,4,5,6,7,8,9,10);
void setup(){
lcd.begin(16,2);
Serial.begin(9600);
lcd.clear();
lcd.print(“Hello,Cathy Lee!”);
}
char serialreceive;

void loop(){
if(Serial.available()){
delay(100);
while(Serial.available()>0){
serialreceive=Serial.read();
if (serialreceive==‘R’)
{lcd.clear();
lcd.print(“oh,yeah!”);
Serial.print(“Hello”);}
else
if (serialreceive==‘L’){
// lcd.clear();
lcd.setCursor(3,2);
lcd.print(“wonderful!”);
Serial.print(“Get it!”);
}
else
if (serialreceive==‘c’)
lcd.clear();
else {
//serialreceive=Serial.read();
//lcd.clear();
lcd.write(serialreceive);
Serial.write(serialreceive);}
}
}

}

Was there a question, or do you want me to move this to the "Exhibition and gallery" section?

AWOL:
Was there a question, or do you want me to move this to the "Exhibition and gallery" section?

And add a couple of pictures and a video, you make a decent tutorial.
