Kontrol servo kanan - kiri per step

Merupakan konfigurasi diagram alir (node-based visual programming) untuk mengontrol pergerakan motor servo bolak-balik (kanan-kiri) berbasis board Arduino Nano.

Berikut adalah rincian komponen dan cara kerja sistemnya:

Komponen Utama (Nodes)

Square Wave Generator (frequency: 0.5): Menghasilkan pulsa detak (clock) periodik setiap 2 detik sekali untuk memicu perubahan posisi.
Boolean Value Switch: Digunakan sebagai sakelar penentu arah gerakan.
- 1 / TRUE: Arah Naik (Up / Kanan)
- 0 / FALSE: Arah Turun (Down / Kiri)
Gerbang Logika (logicAnd & logicNot): Mengarahkan sinyal pulsa dari Square Wave menuju pin UP atau DOWN pada Counter, tergantung status Boolean Switch.
Counter Up/Down: Pusat pengendali sudut pergerakan.
- Step (Langkah): 45 derajat.
- Rentang Nilai: 0 (Min) hingga 180 (Max).
- Reset: Kembali ke angka 0 saat Push Button ditekan.
Output / Output Indicators:
- Servo Motor (Pin 13): Bergerak secara bertahap sesuai keluaran nilai derajat dari Counter.
- Gauge Display & Value Monitor (Serial Log): Menampilkan posisi sudut derajat saat ini secara visual dan teks angka.
- Light Bulb: Menerima input nilai derajat yang sama dari Counter.

Cara Kerja Rangkaian

Sinyal Detak: Square Wave Generator memancarkan pulsa berulang setiap 2 detik.
Logika Arah (Kanan / Naik): Jika sakelar Boolean bernilai TRUE, gerbang logicAnd atas akan aktif. Pulsa clock dikirim ke pin UP Counter, menambahkan sudut motor servo sebesar +45° setiap interval hingga mencapai batas maksimal 180°.
Logika Arah (Kiri / Turun): Jika sakelar Boolean bernilai FALSE, nilai tersebut dibalikkan oleh logicNot sehingga gerbang logicAnd bawah menjadi aktif. Pulsa clock dikirim ke pin DOWN Counter, mengalihkan gerakan untuk mengurangi sudut sebesar -45° hingga mencapai 0°.
Reset Manual: Menekan Push Button akan langsung mengembalikan posisi counter dan servo ke titik 0°.
