Arduino interfacing

[AirGears]

I have managed to get X-Sim to talk to my Arduino controller, I am sure that they are communicating, but I do not know what it is sending, I have tried to display it on an LCD screen and I only get white boxes, I am inexperienced with this subject but am eager to learn, thanks in advance for any assistance

Give me more information. for example code with comments, and the uso config etc.

const int ledPin = 13;
int incomingByte;
#include <LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);
//general setup for inputs and variables
void setup() {
lcd.begin(16, 2);//begins use of LCD screen
lcd.clear();//clears LCD screen prior to program that way there is no old information on it
Serial.begin(9600);//begins serial communication with the computer
}

void loop() {
if (Serial.available() > 0) {//if serial communication is available:
incomingByte = Serial.read();//read what is being sent through serial and save it as variable incomingByte
lcd.write(incomingByte);//write incomingByte on LCD screen
}
if (millis() >5000) {
lcd.clear();//clear LCD screen every 5 seconds to allow new information to display
}
}
that is my code for Arduino
and this should be a picture of X-Sim as it is, if it displays, if not ill have to find another way to make it do so

Ok. I see.

Here is a good very Tutorial for a dashboard. Modify the code for LCD use
