\"\"<\/a>Potansiyometre Nedir?<\/h3>\n

Potansiyometre ayarlanabilir bir diren\u00e7tir. \u00dc\u00e7 bacakl\u0131 bir komponenttir. Biz anlat\u0131m\u0131m\u0131zda d\u0131\u015ftaki u\u00e7lar + ve \u2013 ba\u011flant\u0131lar\u0131n\u0131 temsil ederken ortadaki u\u00e7 ise potansiyometrenin \u00e7evrilmesiyle de\u011fi\u015fen direnci temsil eder.<\/p>\n

Diren\u00e7 de\u011fi\u015ftik\u00e7e analog olarak giden veri artar veya azal\u0131r. Potansiyometre tamamen analog olarak \u00e7al\u0131\u015f\u0131r.<\/p>\n

Potansiyometre ile Led Kontrol\u00fc<\/h3>\n

Potansiyometre 0 de\u011ferini g\u00f6nderirken led s\u00f6n\u00fck olacak, 1023 \u00e7evrilmi\u015f haliyle 255 de\u011ferini g\u00f6nderdi\u011finde ise tamamen yan\u0131yor olacakt\u0131r.<\/p>\n

Arduino ile Potansiyometre Kullan\u0131m\u0131<\/strong><\/em>\u00a0yaparken ADC kullan\u0131m\u0131 gerekecektir. Arduino i\u00e7erisinde dahili olarak 10 Bit \u00e7\u00f6z\u00fcn\u00fcrl\u00fc\u011fe sahip\u00a0Analog Digital Converter Mod\u00fcl\u00fc<\/strong><\/em>\u00a0bulunmaktad\u0131r. Yani 0 ile 1023 aras\u0131nda s\u0131f\u0131r da dahil olmak \u00fczere toplamda 1024 de\u011fere sahiptir.<\/p>\n

Ancak\u00a0Arduino ile Potansiyometre Kullan\u0131m\u0131<\/strong><\/em>\u00a0gerekti\u011finde PWM yani Analog sinyali taklit eden dijital sinyaller olarak kullanabilmek i\u00e7in 0-1023 aral\u0131\u011f\u0131n\u0131 0-255 aral\u0131\u011f\u0131na d\u00f6n\u00fc\u015ft\u00fcrmemiz gerekir.<\/p>\n

otansiyometre analog veri g\u00f6nderir.\u00a0Arduino analog veriyi ADC \u00fczerinden 0-1023 de\u011fer aral\u0131\u011f\u0131nda okur.\u00a0Bunu PWM \u00fczerinden g\u00f6nderirken ise 0-255 de\u011fer aral\u0131\u011f\u0131n\u0131 kullanmam\u0131z gerekir.<\/p>\n

Bunun i\u00e7in de Map komutu yani haritalama komutu kullanaca\u011f\u0131z.<\/p>\n

Arduino ile Potansiyometre Kullan\u0131m\u0131: Map Komutu Nas\u0131l Kullan\u0131l\u0131r?<\/h3>\n

Map komutu ile d\u00f6n\u00fc\u015ft\u00fcrmek istedi\u011fimiz de\u011fi\u015fkeni ve d\u00f6n\u00fc\u015fecek iki aral\u0131\u011f\u0131 ayn\u0131 sat\u0131rda belirtiyoruz.<\/p>\n

Potansiyometreyi temsil eden \u201cpot\u201d de\u011fi\u015fkeninin kar\u015f\u0131s\u0131na Map Fonksiyonu i\u00e7in Map Komutunun s\u00f6z dizimi a\u015fa\u011f\u0131daki gibidir:<\/p>\n

\"\"<\/a><\/p>\n

Potansiyometre \u00fc\u00e7 ayakl\u0131 bir eleman olup anlat\u0131m\u0131m\u0131zda d\u0131\u015ftaki bacaklar\u0131 + ve \u2013\u2018yi temsil ederken ortadaki ayak ile potansiyometredeki de\u011fi\u015fim g\u00f6zlenir. + ve \u2013\u2018nin y\u00f6n\u00fc sabit de\u011fildir. Biz nas\u0131l ba\u011flarsak ba\u011flant\u0131 \u015fekline g\u00f6re de\u011fer art\u0131\u015f\u0131 ya da d\u00fc\u015f\u00fc\u015f\u00fc olur.<\/p>\n

De\u011fer de\u011fi\u015fimi orta ayaktan okundu\u011fu ve bu de\u011fer de Analog oldu\u011fu i\u00e7in Arduino Uno\u2019nun A0 pinine giri\u015fini yap\u0131yoruz. Di\u011fer bacaklar + ve \u2013 konumunda.<\/p>\n

\u015eu anda Potansiyometreden Arduino\u2019ya analog de\u011fer g\u00f6nderiyoruz. Arduino bunu ADC \u00fczerinden okudu\u011fu ve 10 Bit \u00e7\u00f6z\u00fcn\u00fcrl\u00fc\u011fe sahip oldu\u011fu i\u00e7in 0-1023 de\u011fer aral\u0131\u011f\u0131nda okuyabilmektedir.<\/p>\n

Fakat PWM Sinyalleri ise veri g\u00f6nderimini 0-255 de\u011fer aral\u0131\u011f\u0131nda yapabilmektedir.<\/p>\n

Bu durumda arada bir de\u011fer d\u00f6n\u00fc\u015ft\u00fcr\u00fcc\u00fc fonksiyon yani map komutunu kullanmam\u0131z gerekir. B\u00f6ylece potansiyometreden gelen 0-1023 aral\u0131\u011f\u0131n\u0131 0-255 aral\u0131\u011f\u0131na \u00f6l\u00e7ekleyebilir ve bu de\u011feri PWM \u00fczerinden g\u00f6nderilebilir hale getirebiliriz.<\/p>\n

E\u011fer bu de\u011fi\u015fimi yapmazsak potansiyometreden gelen de\u011fer ile led veya buzzer\u2019a giden de\u011fer aras\u0131nda tutars\u0131zl\u0131k olur. Potansiyometrenin bir turunda PWM 4 kez tekrarlan\u0131r. Potansiyometrede bir tam tur PWM\u2019de 4 tur anlam\u0131na gelir. 0-1023 ile 0-255 \u2018ten dolay\u0131 b\u00f6yle bir durum ortaya \u00e7\u0131kar.<\/p>\n
