  buttonDownState = digitalRead(switchDownPin);

  if (buttonUpState != lastButtonUpState)
  {
    if (buttonUpState == HIGH)
    {
      if(counter == 9)
      {
        counter = -1;
      }
      counter++;
      Serial.println(counter);
      changeNumber(counter);
      delay(300);
    }
    else
    {
        Serial.println("OFF");
    }
   delay(50);
  }


  if (buttonDownState != lastButtonDownState)
  {
    if (buttonDownState == HIGH)
    {
      if(counter == 0)
      {
        counter = 10;
      }
      counter--;
      Serial.println(counter);
      changeNumber(counter);
      delay(300);
    }
    else
    {
        Serial.println("OFF");
    }
   delay(50);
  }
  changeNumber(counter);
}

void changeNumber(int buttonPress)
{
  switch (buttonPress)
  {
    //number 0
    case 0:

      );
      break;
  }
}
    4. sambungkan arduino ke pc gambar di bawah ini:

5. HASIL PRAKTEK

6.   KESELAMATAN KERJA
        1.  Menggunakan baju praktek
        2.  Menaati peraturan yang berlaku dalam laboratorium/bengkel
        3.  Menggunakan fasilitas dengan tertib
        4.  Tidak bercanda dalam kegitan praktek
        5.  Membersihkan ruangan kerja setelah praktik berakhir
        6. Mematikan komputer dan sumber listrik yang tidak dipakai

7.   KESIMPULAN
        Dari praktek ini kita dapat membuat counter up dan down dalam pembuatan projek ini. dan kita bisas mengenbangkan imajinasi dalam pembuatan projek ini.
