Tugas Akhir Water Flow Sensor On Arduino Uno R3 Galih NFS

Mas boleh minta email nya, buat sharing berkaitan dengan video-nya. Saya sedang mencoba buat juga
Terimakasih

Mas, apa bisa sensor ini dapat menghidupkan saklar pada volume tertentu yg sdh kita tentukan total volumenya? trims

lanjukannnn gannnnn

minta lcd connection

mantap mas . jadi bisa memperhitungkan waktu untuk ngisi air . jadi bisa di tinggal gk harus ngelihatin air nya aja ,,
#saran ane mas , hati2 lain kali kalau ingin buat video demo jgn sampe kaya gtu lagi hehe untuk gk rusak tuh laptop , kalo rusak bisa berabeee wkwkkw

mantap mas, bisa bagi kontaknya mas? saya mau tanya tanya mas kalau bisa, makasih

Cara kalibrasinya gimana om

fuck off
