Mengakses Slide Potesio Interface 7segment
Pada kesempatan kali ini saya akan menjelaskan mengenai bagamana cara mengakses slide potensio dengan menggunakan arduino dengan interface 7segment, jadi ada nilai yg tertera di 7segment yang akan berubah sesuai kondisi dari posisi slide potensionya. jika posisi dibawah maka nilai rendah lalu jika posisi diatas maka nilai tinggi. untuk lebih jelasnya berikut adalah koding dan daftar komponenya.
a. Arduino Uno
b. Slide Potensio
c. Interface 7Segment
