Ethernet Shield W1500

Ethernet W1500 shield dapat digunakan untuk menghubungkan modul arduino ke dalam jaringan internet melalui koneksi kabel RJ45 (tidak termasuk dalam paket). Penggunaan modul W1500 sangat mudah dan cepat dilakukan, karena pada program IDE arduino sudah terdapat contoh programnya. Sehingga dalam hitungan menit Anda akan dapat melakukannya. Untuk melakukan testing terpisah bagaimana menggunakan Ethernet Shield W1500 silakan merujuk pada posting Testing W1500 Ethernet Shield.

Sensor Ultrasonic HC-SR04

Sensor Ultrasonic HC-SR04

Sensor ultrasonic HC-SR04 adalah salah satu modul yang dapat digunakan pada modul Arduino. Untuk menggunakan sangat mudah dan dalam waktu beberapa menit bisa dilakukan. Bagi yang ingin melakukan testing secara mandiri silakan merujuk posting Simple Arduino and HC-SR04 Example. Datasheet dapat diunduh HC-SR04.

Koneksi pin HC-SR04 adalah:

  • 5V Supply
  • Trigger Pulse
  • Echo Pulse O
  • 0V Ground

seperti terlihat dibawah ini:

Selanjutnya, untuk melakukan testing komponen yang dibutuhkan adalah:

  • 1 unit sensor ultrasonic HC-SR05
  • 4 pin kabel jumper female-male
  • 1 unit modul arduino
  • 1 unit modul ethernet W1500
  • 1 kabel RG45
  • 1 kabel USB

/*
Web Server

A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.

Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)
