Penulis Artikel ini merupakan artikel sementara sebelum dijelaskan secara detail, karena videonya telah diluncurkan jadi perlu adanya kode program untuk yang ingin mencobanya.

Inilah kode programnya
/*Thanks. Remember to visit my Youtube channel
If you don't whant to Serial print the valeus just delete the serial. print lines
and leave just the LCD print ones.
I've used a i2c LCD screen module.
