Seven segmen dengan tombol dan LED dengan awal perinsip kerja nilai seven segmen dimulai dari nilai 320 dan LED pertama aktif dan LED lainnya tidak aktif, saat tombol UP ditekan bersamaan dengan tombol Key ditekan maka akan menghasilkan nilai 320 menjadi 330 maka LED kedua aktif dan LED lainnya tidak aktif sampai dengan nilai 370.
