Merhaba,
anten çalışmalarında kullanmak üzere ihtiyacım olan RF Power metre için bir süredir beklediğim AD8318 modülü gelince projeyi bitirmek lazımdı, bitti ve güzel çalışıyor.
iki önyüz kullandım, üzerinde on off harici switch olmadığından cihaz her açılışında diğer önyüz ile açılıyor.
eklerde 3D çizim ve arduino kodunu aşağıda bulabilirsiniz. 73
