7 Segment merupakan display yang banyak digunakan dalam aplikasi microcontroller. Selain murah, intensitas cahaya 7segment cukup kuat sehingga memudahkan seseorang untuk membaca tampilannya. Untuk menggunakan 7 segment kita harus memakai rangkaian driver, ada beberapa macam rangkaian driver 7segment  yg umum digunakan, salah satunya seperti yg kami dapat dari MYTUTORIALCAFE.COM :

Dalam rangkaian diatas, kita membutuhkan 10 pin microcontroller untuk mengakses dua 7segment.

Pertanyaannya:

bagaimana jika kita masih memerlukan pin-pin microcontroller tersebut untuk membaca data sensor, komunikasi dengan PC dan menggerakkan motor??? tentu jumlah pin microcontroller tidak mencukupi.

Apa kita harus menggunakan dua micro??ini suatu pemborosan.

Jawabannya, kita harus menghemat penggunaan pin microcontroller untuk dispaly (akses 7segment)

Alternatif menarik dalam mengakses 7segment dapat kita lihat dalam rangkaian berikut:

Dengan bantuan IC 74LS164, kita hanya membutuhkan 2 pin microcontroller.
