7. Upload ke Arduino
VI.Keselamatan Kerja
1.Menggunakan workpack
2.Tidak makan/minum di lab
3.Tidak membawa makanan/minuman di lab
4.Mentaati peraturan di lab
VII.Kesimpulan
Siswa dapat membuat program counter up dan counter down dengan 2 push button dengan baik dan benar.Kesalahan yang terjadi adalah kesalahan dalam merangkain dan dapat diatasi dengan membenarkan kesalahan dalam perangkaian tadi.
