I2C and INT0

Hello,

i bought that arduino called NHduino, NHduino - YouTube

i connect the LCD I2C based on that code and picture

#include <LCD.h>
#include <LiquidCrystal_I2C.h>

#include <Wire.h>


LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);

Now the LCD works fine but not the INT0

i have that code and it does not show me anything correct... just stange big numbers

any idea?

  {

    //for tacho---------------------------------------------------
    attachInterrupt(sensorInterrupt, sensorIsr, RISING);
    lastPulseTime = millis();
    timeoutCounter = 0;
  }
}


void sensorIsr()

{
  unsigned long now = millis();
  interval = now - lastPulseTime;
  lastPulseTime = now;
  timeoutCounter = timeoutValue;
  startTime = millis();  //save the time the tacho was read
}

You should provide a link to the LiquidCrystal_I2C library you're using as my version accepts only 3 parameters in the constructor.

Post complete code not just excerpts! The code you posted does not compile and may have lots of errors in the definitions, includes or variable declarations.
