BAB IV PENGUJIAN RANGKAIAN
4.1 PENGUJIAN RANGKAIAN POWER SUPPLAY ADAPTOR PSA
Pengujian rangkaian ini dengan mengukur tegangan keluaran dari power supply menggunakan multimeter digital. Setelah dilakukan pengukuran maka
diperoleh besarnya tegangan keluaran sebesar 5 volt. Setelah itu rangkaian power supply dihubungkan ke sumber arus listrik dan saklar ONOFF nya diaktifkan ke
posisi ON.
4.2 Pengujian Sistem Minimum ATMega 8535
Karena pemrograman robot menggunakan mode ISP In System Programming
mikrokontroler harus dapat diprogram langsung pada papan rangkaian dan rangkaian mikrokontroler harus dapat dikenali oleh program
downloader. Pada pengujian ini berhasil dilakukan dengan dikenalinya jenis mikrokontroler oleh program downloader yaitu ATMega8535.
4.3 Pengujian Sensor LM 35
Sensor ini bekerja dengan cukup baik, Sensor suhu LM 35 dapat mendeteksi suhu suatu ruangan tersebut. Tetapi dalam pengujian ini, sensor yang ditampilkan pada 7
segment berupa data yang tetap yang telah diatur sebelumnya dari push buttom, tetapi setelah kita hidupkan, kita masih dapat juga mengubahnya dengan mengatur push buttom
tersebut.

Pengujian Seven LCD
Untuk menguji rangkaian LCD, maka dibuatlah rangkaian sebagai berikut ini:
Gambar 4.1 Pengujian Rangkaian LCD
Kemudian, pada mikrokontroler dimasukkan program sebagai berikut: regfile = 8535def.dat
crystal = 12000000 Config Lcd = 16 2
Config Lcdpin = Pin , Rs = Portc.1 , E = Portc.0 , Db4 = Portc.4 , Db5 = Portc.5 , Db6 = Portc.6 , Db7 = Portc.7
Cursor Off Cls
Do Locate 1 , 1
Lcd Hello World Loop
Ketika program dieksekusi oleh mikrokontroler, maka pada display LCD akan muncul tulisan “hello, world” pada layar LCD.
