Counting Machine




Sistem penghitung jumlah banyak orang yang lewat pada suatu gate atau pintu masuk, tes



Project ini adalah suatu sistem penghitung jumlah banyak orang yang yang lewat pada suatu gate atau pintu masuk, sistem ini dibuat dengan menggunakan intel galileo dengan input sebuah photo sensor , yang dimana datanya akan dikirim ke cloud (geeknesia).

Ini adalah sample code pada project ini menggunkan Arduino IDE
