UART nedir?<\/h3>\n
\n\n

UART (Universal Asynchronous Receiver-Transmitter) noktadan noktaya bir seri\u0307 i\u0307leti\u0307\u015fi\u0307m<\/a> G\u00f6m\u00fcl\u00fc sistemlerde yayg\u0131n olarak kullan\u0131lan protokol. Verileri e\u015fzamans\u0131z olarak g\u00f6ndermek ve almak i\u00e7in sadece iki hat (TX (g\u00f6nderme) ve RX (alma)) kullan\u0131r, yani bir saat sinyali gerektirmez. \u00c7o\u011fu mi\u0307krodenetleyi\u0307ci\u0307ler<\/a> gibi ESP32<\/a>, STM32 ve Arduino<\/a> UART deste\u011fi sayesinde tek sens\u00f6rl\u00fc kurulumlar i\u00e7in idealdir.
\u00d6rnek: UART aray\u00fcz\u00fcne sahip bir lazer mesafe sens\u00f6r\u00fc, \u00f6l\u00e7\u00fcm verilerini bir drone \u00fczerindeki u\u00e7u\u015f kontrol cihaz\u0131na g\u00f6nderir.<\/p>\n\n<\/div>\n<\/div>\n

I2C nedir?<\/h3>\n
\n\n

I2C (Entegre Devreler Aras\u0131), ayn\u0131 kart \u00fczerindeki \u00e7ipler aras\u0131nda k\u0131sa mesafeli ileti\u015fim i\u00e7in tasarlanm\u0131\u015f senkronize, \u00e7ok cihazl\u0131 bir ileti\u015fim protokol\u00fcd\u00fcr. \u0130ki hat kullan\u0131r -CL (saat) ve SDA (veri)- ve her birine benzersiz bir adres atayarak tek bir ana cihaz\u0131n birden fazla ba\u011f\u0131ml\u0131 cihazla ileti\u015fim kurmas\u0131n\u0131 sa\u011flar. Bu sayede bir sistemde birden fazla sens\u00f6r kullan\u0131ld\u0131\u011f\u0131nda yerden tasarruf sa\u011flayan bir \u00e7\u00f6z\u00fcmd\u00fcr.
\u00d6rnek: Bir robotik kol, engelleri \u00e7e\u015fitli a\u00e7\u0131lardan tespit etmek i\u00e7in birden fazla I2C lazer mesafe mod\u00fcl\u00fc kullan\u0131r.<\/p>\n\n<\/div>\n<\/div>\n

USB nedir?<\/h3>\n
\n\n

USB (Evrensel Seri Veri Yolu), en yayg\u0131n olarak PC ve diz\u00fcst\u00fc bilgisayarlarda kullan\u0131lan y\u00fcksek h\u0131zl\u0131, tak ve \u00e7al\u0131\u015ft\u0131r bir ileti\u015fim standard\u0131d\u0131r. UART ve I2C'nin aksine, USB ayn\u0131 kablo \u00fczerinden hem veri hem de g\u00fc\u00e7 sa\u011flar, bu da onu masa\u00fcst\u00fc veya laboratuvar ortamlar\u0131 i\u00e7in ideal hale getirir. Genellikle veri kayd\u0131, sens\u00f6r kalibrasyonu i\u00e7in veya sens\u00f6r bir GUI veya veri toplama yaz\u0131l\u0131m\u0131 arac\u0131l\u0131\u011f\u0131yla \u00e7al\u0131\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda kullan\u0131l\u0131r.
\u00d6rnek: Bir m\u00fchendis, \u00f6zel bir yaz\u0131l\u0131m kullanarak mesafe de\u011fi\u015fikliklerini ger\u00e7ek zamanl\u0131 olarak izlemek i\u00e7in bir USB lazer sens\u00f6r\u00fcn\u00fc bir PC'ye ba\u011flar.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n
