Prinsip Operasi

Dumasar kana prinsip optik. interior na gaduh LED pikeun 1 pc, triode panampi photosensitive pikeun 2pcs; sareng sisi sanésna ngagaduhan hiji tempat teduh silinder; sapertos anu dipidangkeun dina gambar:

Diagram Sirkuit

Ku ngiuhan cylindrical tetep kaluar LED, sarta tube panarima photosensitive pikeun detecting RPl-1031 kaayaan ayeuna.
Nalika RPl-1031 rotates kana kaayaan ditémbongkeun saperti di handap, LED ieu shadowed ku ngiuhan; jeung dua triodes panarima photosensitive teu bisa nampa cahaya; aranjeunna bakal kaluar state.output tingkat low; dua palabuhan GPIO duanana kaluaran tingkat low.

Nalika RPl-1031 rotates kana kaayaan ditémbongkeun saperti di handap, salah sahiji triode photosensitive ieu shadowed, cahaya dipancarkeun ku LED ngan bisa ditarima ku hiji lianna; hartina triode photosensitive di luhur hurung, sarta triode photosensitive handapeun sisi pareum; lajeng dua GPIO palabuhan kaluaran masing-masing kaluaran tingkat tinggi na tingkat low.
Nalika RPl-1031 rotates kana kaayaan ditémbongkeun saperti di handap, ngiuhan teu kalangkang dioda bakal caang, dua triodes photosensitive bisa nampa cahaya; lajeng sakabéh éta bakal on.both dua palabuhan GPIO kaluaran tingkat tinggi.

Nalika RPl-1031 rotates kana kaayaan ditémbongkeun saperti below.this kaayaan ngarugikeun pedaran 4 dua GPIO port tingkat kaluaran bakal antar cahnged.
