LCD (I2C) as an serial monitor.

goodday all,

i have question little project i'm making school.
i'm starting user, , ive got little background programming , building cerquit boards.

what project?:
i want put output of optical senor (i can read out on serial monitor) on lcd i2c chip.

this code ive got far.

code: [select]


#include <wire.h>
#include <liquidcrystal_i2c.h>
liquidcrystal_i2c lcd(0x27,16,2);

const int led = 13;
int tcrt;

void setup(){
   // set lcd's number of columns , rows:
 lcd.init();
 lcd.backlight();
 // initialize serial communications:
 serial.begin(9600);
 pinmode (led, output);
}

void loop(){
 tcrt = analogread(a0);
 serial.println(tcrt);
 analogwrite(led, tcrt/4);
 // when characters arrive on serial port...
 if (serial.available()) {
   // wait bit entire message arrive
   delay(100);
   // clear screen
   lcd.clear();
   // read available characters
   while (serial.available() > 0) {
     // display each character lcd
     lcd.write(serial.read());
   }
 }
}




i hope guys can me.

tnks,
