Arduino ile Radar Devresi, Merhaba arkadaş Arduino ile Radar Devresi yapılışını anlatacagım. Paylaşacagım bu devrenin çalışır şeklini videodan izleyebilirsiniz.

Arduino ile radar devresinde hc04 bir ultrasonic sensör kullandım. Biliyorsunuz ki bu sensör ses dalgaları yollayarak algılama yapıyor. Bu devrede radarın görüş alanına giren cismi anlık olarak processing programı ile görebiliyoruz. Askeri radar sistemlerinin amatör olarak yapılmış halidir

Piyasa olan arduinoyla radar devrelerine ek olarak bir acil aydınlatma ekledim. Arduinomuz alan taraması yaparken cisim çok yakınan geldiginde alarm niyetinde bir ışıklandırma koydum tabi siz bu ışıklandırmayı kaldırıp isterniz zil koyun.

Işıklandırma için arduinonun 13. bacagını kullandım. Programda da bunu belirttim. Arduinonun bacagını direkt olarak ışıklandırmaya takmadım çünkü ışıklandırma aşırı akım çekecegi için bacagını yaanardı bu yüzden bc639 bir transistörü tetikledim ışıklandırmayı ordan dogru besledim.

Adding +1 (i) each time through the loops to move 1 degree matching the one degree of servo movement
cos is for the x left to right value and sin calculates the y value
since its a circle we plot our lines and vertices around the start point for everything will always be the center.

“Arduino ile Radar Devresi” üzerine 1 yorum

  1. devreler dedi ki:

    Arduino Ile Radar Devresi nde cisim yaklaştıgında 220v luk lambayı nasıl yakarız? Aklıma röle ile yol vermek geldi.
    Röle kullanmayıp transistör kullansak, Transistör önerisinde bulunabilir misiniz?
