TP 1 uP uC M2
1. Prosedur [Kembali]
- Rangkai sesuai gambar percobaan dengan inputnya yaitu sensor Soil Moisture dan outputnya yaitu LED RGB dan Motor Stepper
- Buatlah program dengan konfigurasi pin input dan output berdasarkan pada pin GPIO STM32 yang telah dirangkai sebelumnya. Kemudian buatlah program untuk menghasilkan output LED RGB sesuai kondisi yang telah ditentukan
- Run simulation dan lihat perubahan ketika sensor soil moisture mendeteksi kelembapan basah
- Program selesai
- STM32F103C8
- LED RGB
- Soil Sensor
- Motor Stepper
- Resistor
- Kapasitor
- ULN2003A
3. Rangkaian Simulasi dan Prinsip Kerja [Kembali]
Rangkaian ini bekerja dengan sensor soil moisture sebagai input serta LED RGB dan Motor Stepper sebagai output.
Sensor soil moisture jika mendeteksi basah, maka akan menghasilkan output LED RGB akan berwarna merah dan motor stepper akan bergerak.
