Lcd Display For Ezb4 - Using Arduino Mini As Controler

Hello again,

I have created an LCD Display for the EZB4.

This is a very cheep and easy project.

You will need

1 LCD display ( my code is set up for 2 line 16 char display)
here are 5 of them for about 10 bucks USD

1 Arduino ( any model will work but i recomend the Pro MINI)
Here is a listing of them on ebay


Oh here is the wiring . again I am using the pro mini . this is showing and UNO board. the pin outs are the same.





To wire your LCD screen to your Arduino, connect the following pins:
LCD RS pin to digital pin 12
LCD Enable pin to digital pin 11
LCD D4 pin to digital pin 5
LCD D5 pin to digital pin 4
LCD D6 pin to digital pin 3
LCD D7 pin to digital pin 2
Additionally, wire a 10K pot to +5V and GND, with it's wiper (output) to LCD screens VO pin (pin3).






Arduino code:

Code:

// LCD and Arduino to EZB4
// Project Created by Luis A. Vazquez
// www.dragontear.com

#include <LiquidCrystal.h>
String content = "";
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
  Serial.begin(9600);
  lcd.begin(16, 2);
  lcd.setCursor(0,0);
  lcd.print("EZB4 LCD Display");
  lcd.setCursor(0,1);
  lcd.print("By DragonTear");
}
void loop() {
  readSignalFromComp();
}

void readSignalFromComp() {
  if (Serial.available()) {
  delay(100);
  while (Serial.available() > 0) {
  int temp = Serial.read();

   
  Serial.print("Debug:");
  Serial.println(temp);  

  if (temp == 17){lcd.clear();}
      
  if (temp == 18){lcd.setCursor(0,0);}
      
  if (temp == 19){lcd.setCursor(0,1);}
    
  if (temp > 31){  lcd.write(temp);   }
    
    }
  }
}
