Bu projede ESP01 (ESP8266-01) Mod\u00fcl\u00fc ile Openweathermap sitesinden al\u0131nacak hava durumu bilgisi, G\u00fcncel zaman ve d\u00f6viz kurlar\u0131n\u0131 birlikte kullan\u0131ld\u0131\u011f\u0131 bir program\u0131 anlataca\u011f\u0131m.<\/p>\n

Bir \u00f6nceki yaz\u0131mda ise UNIXTIME konusunu anlatm\u0131\u015ft\u0131m. O yaz\u0131y\u0131 haz\u0131rlamaktaki amac\u0131m gelen verilerde UNIXTIME kodlar\u0131 bulunmas\u0131yd\u0131. Bu kodlar\u0131 nas\u0131l \u00e7\u00f6zebilirim diye sorgulad\u0131\u011f\u0131mda sadece Arduinoda k\u00fct\u00fcphane deste\u011fi olabilir dedim. Fakat k\u00fct\u00fcphanesiz nas\u0131l \u00e7\u00f6zerim dedim ve bu yaz\u0131y\u0131 yazm\u0131\u015ft\u0131m.\u00a0<\/strong><\/a><\/p>\n

Sonras\u0131nda bu projeye ba\u015flad\u0131m. Tabii ki yol al\u0131rken farkl\u0131 se\u00e7enekler oldu\u011funu g\u00f6rd\u00fcm. Farkl\u0131 se\u00e7enekleri yaz\u0131da g\u00f6receksiniz.
\nHava durumu program\u0131 yapmak i\u00e7in bilgilerin internette abone oldu\u011funuz bir siteden al\u0131nmas\u0131 yeterli oluyor. Bu sitelerin API destekleri var. Kullan\u0131c\u0131lar bu i\u015flem i\u00e7in siteye kay\u0131t olurlar ve kendilerine bir g\u00fcvenlik anahtar\u0131 verilir.
\nBu bilgileri isterseniz WEB sitenizde, isterseniz de evde yapaca\u011f\u0131n\u0131z cihazlarda kullanabilirsiniz.
\nGenelde bu projeleri yapanlar ESP mod\u00fcllerini kullan\u0131r. En k\u00fc\u00e7\u00fck mod\u00fcl ESP01 denilen ESP8266-01 mod\u00fcl\u00fcd\u00fcr.<\/p>\n

Bu mod\u00fcl\u00fc direkt programlayarak kullanabildi\u011fimiz gibi, Arduino ya da di\u011fer mikrokontrolc\u00fclerle de kullanabiliriz. Sadece 4 adet GPIO kullan\u0131ma a\u00e7\u0131ld\u0131\u011f\u0131ndan bundan daha fazla giri\u015f \u00e7\u0131k\u0131\u015f pimine ihtiya\u00e7 varsa o zaman bir arduino ya da di\u011fer mikrokontrolc\u00fclerle kullanman\u0131z yerinde olacakt\u0131r.
\nArduino ile ESP mod\u00fclleri programlamak i\u00e7in bu yaz\u0131ma g\u00f6z atman\u0131z yerinde olacakt\u0131r.<\/strong><\/a><\/p>\n

Yapaca\u011f\u0131m projede EASYLCD<\/strong><\/span> 4×20 karakter LCD kullanaca\u011f\u0131mdan, sadece LCD kontrol i\u00e7in tek bir pim yeterli olacakt\u0131r, ESP01 mod\u00fcl\u00fcn\u00fc kendi ba\u015f\u0131na \u00e7al\u0131\u015facak \u015fekilde ARDUINO IDE ile programl\u0131yorum.
\nBunun yan\u0131 s\u0131ra I2C OLED ya da ba\u015fka ekranlar olursa, ESP01 mod\u00fcl\u00fc bunlar\u0131 da 2 pim ile kontrol edebilir.<\/p>\n

Programlamada dikkat etmeniz gereken bir durum var. Bu da ESP01 kullan\u0131rken, HTTP<\/span> ya da HTTPS<\/span> olan sitelere ba\u011flant\u0131 fark\u0131. \u015eayet HTTPS kullan\u0131lacaksa, ESP security k\u00fct\u00fcphanesini<\/span> kullanman\u0131z gerekir. Bu k\u00fct\u00fcphaneyle ilgili \u00f6rnekler internette bulunmaktad\u0131r.<\/p>\n

Openweathermap sitesinden bilgi al\u0131yorum. Bu site HTTP<\/span> ve HTTPS<\/span> olarak API KEY<\/span> ile bilgi g\u00f6nderebiliyor. Bundan dolay\u0131 SECURITY k\u00fct\u00fcphanesini kullanmayaca\u011f\u0131m.<\/p>\n

Bu site zaman bilgisi olarak bulundu\u011funuz zaman\u0131 vermiyor.<\/span><\/strong> Sadece bilgi g\u00fcncelleme zaman\u0131n\u0131 ve g\u00fcn do\u011fumu ile g\u00fcn bat\u0131m\u0131 zamanlar\u0131n\u0131 veriyor.
\nYani bir de ger\u00e7ek anl\u0131k zaman\u0131 alman\u0131z gerekebiliyor. Bunu da genellikle bu tip projelerde NTP \u00fczerinden al\u0131nan anl\u0131k zaman bilgisi ile sa\u011fl\u0131yorlar.<\/p>\n

\u00d6ncelikle Projemde neler var bunlar\u0131 g\u00f6relim.<\/span><\/strong>
\n1-) Openweathermap sitesinden anl\u0131k hava durumu bilgisini almak. ( Bu site free limiti dakikada 60 ileti\u015fim hakk\u0131d\u0131r. Arka arkaya bundan daha h\u0131zl\u0131 bir ileti\u015fim kurarsan\u0131z bilgi gelmeyecektir. Ya da site taraf\u0131ndan ikaz edileceksiniz bunu da alg\u0131lamazsan\u0131z api devre d\u0131\u015f\u0131 kalabilir. )<\/p>\n

2-) Zaman bilgisi. NTP den al\u0131nan zaman bilgisi olabilir ama ben kendi PHP sunucumun zaman bilgisini ald\u0131m. (Her sunucu zaten kendi saatini devaml\u0131 g\u00fcncel tutar.)<\/p>\n

3-) TCMB kur bilgileri : TCMB den XML format\u0131nda al\u0131nan d\u00f6viz bilgilerinden istedi\u011fimi yans\u0131tabilirim.
\n(Fakat ben buna ESP ile direkt ula\u015fmayaca\u011f\u0131m PHP \u00fczerinden yapaca\u011f\u0131m. )<\/p>\n

Projede ESP ile \u00d6nce Openweathermap sitesine ba\u011flan\u0131p gelen bilgiyi par\u00e7alar\u0131m. Sonras\u0131nda NTP den gelen zaman bilgisini \u00e7\u00f6zerim. Sonras\u0131nda ise TCMB ye ba\u011flan\u0131p kur bilgilerini alabilirim. Bu bilgileri de par\u00e7alay\u0131p de\u011fi\u015fkenlere aktarabilirim.
\nBunu yapmak i\u00e7in 3 kez internete ba\u011flan\u0131p bu bilgileri al\u0131p bunlar\u0131 par\u00e7alayarak de\u011fi\u015fkenlere koymam gerek. ESP program\u0131m olduk\u00e7a \u015fi\u015fecek ve bunlar\u0131 \u00e7\u00f6zmek i\u00e7in \u00e7ok \u00e7aba harcayacak.
\nAyr\u0131ca gelen bilgideki UNIXTIME kodlar\u0131n\u0131 da \u00e7\u00f6zmem gerekecek. Bunu da ya k\u00fct\u00fcphaneyle ya da internetten otomatik \u00e7evirerek yapmam gerek. ( UNIXTIME yaz\u0131mda se\u00e7eneklerinizi g\u00f6rebilirsiniz.<\/span> )<\/p>\n

Ben de t\u00fcm bu ad\u0131mlar\u0131 PHP dosyas\u0131na yapt\u0131r\u0131p, sonras\u0131nda istedi\u011fim bilgileri g\u00f6ndermesini s\u00f6yledim. Hem de istedi\u011fim formatta. Bilgileri kolay olsun diye JSON format\u0131nda istedim ve ay\u0131rarak de\u011fi\u015fkenlere aktard\u0131m. ESP program\u0131m olduk\u00e7a basit ve rahat oldu.<\/p>\n

Sizlere videoda her iki durumu da g\u00f6stermeye \u00e7al\u0131\u015faca\u011f\u0131m.<\/span><\/p>\n

Daha \u00f6nce openweathermap sitesinin http ile bilgi g\u00f6nderebildi\u011fini yazm\u0131\u015ft\u0131m. Ayr\u0131ca bu yaz\u0131lan adres linkinde baz\u0131 ayarlanmalar da yapabilirsiniz.<\/p>\n
