MEMBUATPROGRAM PORT PARALEL LED BERJALAN DENGAN VB

1. Buatlah hardwarenya dengan 12 buah led dimana 8 led pertama sambungkan dengan pin data (2-9) dan 4 led trakhir sambungkan dengan pin control (1,14,16,17) jangan lupa tambahkan resistor dan penyambungan system katoda.

2. Buat project baru kemudian tambahkan 12 shape untuk simulasi lednya, 1 label untuk judul kemudian 5 commandbutton dan 4 buah timer.

3. Kemudian desain lah menjadi seperti gambar berikut :

4. Atur properties masing-masing komponen seperti untuk shape backstyle ubah menjadi 1-opaque kemudian backcolornya pilih warna putih kemudian unutk timer semua interval beri nilai 100 dan dalam keadaan false.

5. Save project dan Form di folder yang sama lalu copykan inpout32.dll pada folder tempat penyimpanan tersebut.

6. Masukkan kode program seperti dibawah ini :

Private Declare Function Inp Lib "inpout32.dll" _

Alias "Inp32" (ByVal PortAddress As Integer) As Integer

Private Declare Sub Out Lib "inpout32.dll" _

Alias "Out32" (ByVal PortAddress As Integer, ByVal value As Integer)

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
