Ethernet Üzerinden Hava Sıcaklığı takibi – 2

Arduino ile yapabilecekleriniz hayal gücünüze kalmıştır. Bu projemizde internet üzerinden ölçmek istediğiniz yerin sıcaklı ve nem takibi yapılabilir. Ayrıca LCD bağlantıı ile aynı zamanda LCDden bilgileri görebilmekteyiz. Verilere göre kontol etmek istediğiniz herhangi bir cihaz bağlanabilir

Bağlantıda dikkat edilmesi gereken noktamız DHT11 arduino bağlantısı 8. pin den sağlanmaktadır.Aşağıdaki resimde LCD daha sonraki kullanacağım proje için orada.

Programı direk koydum, kopyalayıp arduinomuza yüklemeniz yeterli olacaktır. Programda ip adresi olarak 192.168.1.177 kullanılmıştır burada istediğiniz herhangi bir IP kullanabilirsiniz. Kullanacağınız IP adresi bilgisayarınızın IP gurubu ile aynı olmalıdır.

/*
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)
