3. Rangkaian Simulasi dan Prinsip Kerja [Kembali]


Prinsip Kerja:

Pada percobaan 6 kondisi 1 digunakan input berupa sensor suhu LM35 yang dihubungkan ke pin A0 arduino dan button dihubungkan pada pin A1- A5 arduino. Input suhu berfungsi untuk memberikan kondisi dimana ketika suhu besar dari 30, maka motor akan berputar ke kanan, sedangkan button berfungsi untuk mengatur pergerakan motor sesuai dengan sudut- sudut atau langkah- langkah sudutnya. output dari arduino pertama pin 8- 11 dihubungkan dengan LN2003A, yaitu driver untuk menjalankan motor stepper. selain itu pin arduino juga dihubungkan dengan seven segment sebagai output, yang mana 7 segment akan menampilkan suhu LM35.
