1. Prosedur [Kembali]

1. Buka proteus dan siapkan sofware STM32CubeIDE.
2. Buat rangkaian dan sambungkan komponen sesuai kondisi di proteus.
3. Untuk software STM32CubeIDE konfigurasi pin GPIO.

3. Rangkaian Simulasi dan Prinsip Kerja[Kembali]

• Rangkaian 

• Prinsip Kerja :

    Buatlah rangkaian pada proteus seuai dengan kondisi dipilih. hubungkan soil sensor ke pin input stm32, lalu hubungkan rgb led ke pin output dari stm32, setelah itu hubungkan juga uln2003a yang mana sebagai driver motor stepper ke pin output stm32. Kemudian buatkan codingannya sesuai kondisi pada sofware STM32CubeIDE, lalu di convert ke bentuk .hex agar filenya dimasukkin ke dalam proteus pada stm32.

Sensor Soil Moisture bekerja dengan mengukur resistansi tanah. Semakin basah tanah, resistansi menurun dan tegangan output sensor meningkat (pada mode analog). Sinyal dari sensor masuk ke pin analog STM32 (misalnya PA0). STM32 membaca nilai ADC tersebut.

Mikrokontroler memproses nilai tersebut dan membandingkan dengan ambang batas (threshold). Contohnya:

Jika ADC > nilai threshold → tanah dianggap basah.

Jika ADC < threshold → tanah dianggap kering.

Jika tanah basah, STM32 memberikan logika LOW ke pin biru LED RGB, sehingga warna biru menyala. Sedangkan jika tanah tidak basah, maka LED tidak menyala atau bisa diarahkan untuk menyala warna lain (misalnya merah untuk kering – walaupun tidak diminta di soal)
