Arduino ile 433 mhz RF Projesi
Arduino ile standart bir 433 Mhz kumandayı okuyabiliriz (encode). Aldığımız kod ile bir röle kontrol edebilir yada bir mosfet yardımı ile şerit led kısıp açabiliriz. Şimdilik Sadece kodu okuyacağız.
Malzeme Listesi
- 433 Mhz RF Alıcı Modülü
- Arduino ProMini 328
- 433 Mhz Kumanda
- RC Switch kütüphanesi (indir)
Ürünleri aliexpress üzerinden Çinden alırsanız 15 TL kadar tutar.
Arduino Yeni Kütüphanenin Eklenmesi
RC Switch kütüphanesini GitHub dan indirmek için açılan sayfada 
a tılıyoruz gelen kütüphaneyi Arduino Kurulum klasörümüzün içinde bulunan libraries klasörünün içine kopyalıyoruz.
Kablo Bağlantı Şeması
Kabloları şemada görüldü bağlıyoruz.
Kullanılan RF Alıcının anten boyu 173 mm olmalı ayrıntı için tıklayın .
- Data Pin – Dijital Pin 2 ye
- GND – Grounda
- VCC – 5V a
Örnek kodumuzu çalıştırıyoruz
| #include <RCSwitch.h>
RCSwitch mySwitch = RCSwitch(); void setup() { void loop() { int value = mySwitch.getReceivedValue(); if (value == 0) { mySwitch.resetAvailable(); |
Kodu Arduino IDE de File – Example – Rc Switch içinde bulabilir yada buradan kopyalayıp yapıştırabilirsiniz. Eğer bağlantıları doğru yaptıysanız ve kumandanız 433 Mhz ise butona bastığınızda serial monitörde aşağıdaki gibi bir çıktı almanız gerekir.
Eğer serial monitörde bir şey görünmüyorsa öncelikle bağlantıları kontrol edin. Doğru bağladığınıza eminseniz başka bir RF kumanda deneyin. Hala çalışmıyorsa kızın ve onu cezalandırın 🙂

Kumanda nereden alabilirim ? Siz satiyormusunuz ?

Perpa Ticaret Merkezi yada Karaköy Menevşe hanı tavsiye ederim . Online elcik kumanda yazarsanız ürünü sonuçlar da bulabilirsiniz.

anten boyu cok onemli tam olması lazım 173mm onun dışında aklıma bir şey gelmiyor. <birde entegreli alıcı var onu denemenizi öneririm . http://www.f1depo.com/Rxb12-433-mhz-Alici-Receiver,PR-1641.html da var ben bunu kullanıyorum.
