Arduino Ethernet

KONTROL LED BERBASIS WEBSITE DENGAN ARDUINO + ETHERNET ENC28J60

Hi Sobat BI,
Kehadiran IoT (Internet of Things) menuntut semua perangkat (devices) untuk bisa terkonek ke internet. Terdapat beberapa pilihan agar kita bisa terkonek ke internet jika dipandang dari Layer 1 OSI physical layer, yaitu wired dan wireless. Pada kesempatan ini, kami akan memberikan tutorial agar devices kita (Arduino) bisa terkonek ke jaringan secara wired atau kabel.

ALAT DAN KOMPONEN

  1. Arduino (dalam tutorial ini Mega)
  2. Ethernet Board ENC28J60
  3. Kabel Jumper
  4. Kabel RJ45
