I2C LCD 2×16

$3.00

Conexionado de hardware

La conexión del LCD se queda de la sigueinte forma:

  • El pin GND del display al pin GND del Arduino.
  • El pin VCC del display al pin 5V del Arduino.
  • El pin SDA del display al pin analógico 4 del Arduino.
  • El pin SDL del display al pin analógico 5 del Arduino.

USE este codigo para encontrar la direccion del I2C

 

void loop()
{
  byte error, address;
  int nDevices;
  Serial.println(“Scanning…”);
  nDevices = 0;
  for(address = 1; address < 127; address++ )
  {
    // The i2c_scanner uses the return value of
    // the Write.endTransmisstion to see if
    // a device did acknowledge to the address.
    Wire.beginTransmission(address);
    error = Wire.endTransmission();
    if (error == 0)
    {
      Serial.print(“I2C device found at address 0x”);
      if (address<16)
        Serial.print(“0”);
      Serial.print(address,HEX);
      Serial.println(”  !”);
      nDevices++;
    }
    else if (error==4)
    {
      Serial.print(“Unknow error at address 0x”);
      if (address<16)
        Serial.print(“0”);
      Serial.println(address,HEX);
    }    
  }
  if (nDevices == 0)
    Serial.println(“No I2C devices found\n”);
  else
    Serial.println(“done\n”);
  delay(5000);           // wait 5 seconds for next scan
}
y remplezalo en:
LiquidCrystal_I2C lcd(0x27,16,2); // donde dice 0x
