Mambuat Timer Mesin Cuci Analog Menjadi Digital

Pada postingan kali ini saya ingin merubah timer mesin cuci saya dari analog menjadi digital, dikarenakan timer analognya kadang mati sendiri ditengah jalan sepertinya spinnya sudah lemah, setelah saya cari di pasaran untuk tipe spin yang dipakai pada mesin cuci saya itu tidak ada yang sama, jadi dari pada pusing-pusing langsung saja saya ganti menjadi digital menggunakan arduino. dengan begi mesin cuci yang sudah menyebalkan menjadi menyenangkan untuk pengoprasiannya. Oke langsung aja kita ke cara membuatnya.

Pertama Persiapkan alatnya terlebih dahulu:

Arduino Nano
Module Relay 2 Channel
LCD I2C 16×2
Push Button (x4 Buah)
Buzzer
Buat PCB sendiri/Atau disolder langsung untuk semua komponennya juga boleh

Kemudian kalian rangkai alat tersebut seperti pada rangkaian berikut ini.

Setelah itu kalian bisa copykan program berikut ini/kalian bisa download semua filenya di bawah postingan ini.

Jika sudah diupload disini saya buatkan untuk casingnya menggunakan 3D printer dan saya pasangkan pada mesin cucinya.
