BAB IV IMPLEMENTASI DAN ANALISA
Pada bab ini akan dibahas mengenai langkah-langkah pengujian terhadap alat pengkur tinggi badan otomatis. Pengujian dilakukan untuk mengetahui
apakah alat pengukur tinggi badan otomatis yang dibuat sesuai dengan perencanaan dan perancangan system. Pengujian alat ini meliputi:
a. Pengujian program Visual Basic b. Pengujian sensor
c. Pengujian sistem AT89C2051 d. Pengujian rangkaian secara keseluruhan
A. Pengujian Visual Basic
Bagian ini hanya program Visual Basic yang berfungsi sebagai penampilan hasil pengukuran tinggi badan. Serial Port laptop Tx
dihubungkan ke port P3.0 dan Rx dihubungkan ke port 3.1 melalui IC MAX 232 pada mikrokontroler yang berfungsi mengirimkan data hasil pengolahan
untuk ditampilkan dalam bentuk database. Langkah- langkah dalam melakukan pengujian ini adalah
1. Hubungkan downloader AT89C2051 dengan leptop 2. Downloadkan program berikut.
Private Declare Function sndPlaySound Lib winmm.dll Alias sndPlaySoundA ByVal lpszsoundname As String, ByVal uFlags As Long
As Long Private Sub Command1_ClickIndex As Integer
