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

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

  }

}

-Setelah selsai lalu hubungkan ke laptop/pc 

-Selesai,silahkan mencoba.

V.HASIL KERJA

VI.KESELAMATAN KERJA

-Memakai wearpack

-Menaati aturan lab

-Menggunakan alat sesuai fungsi

VII.KESIMPULAN

 

   Dalam praktek ini kita belajar untuk membuat program seven segment counter up dan down dengan dua tombol pushbutton.Kesulitan saya saat praktek adalah ketika membuat program saat membuat angka di seven segment kadang ada yang kebalik-kebalik.
