LPT-AC220V - VB.NET Demo Program

 

 

LPT-AC220V module is a simple module that can be used to control electrical appliances through the computer parallel port.

This module is suitable for you who are studying programming interface via the parallel port. In addition to cheap, this module can be used on any computer that has a parallel port.

Regardless of the operating system used and any programming language used, this module can be used easily.

Here are examples of electrical equipment control programs through the parallel port using the LPT module-AC220V the listing program you can have by commenting on this post.

 

The program still uses the parallel port driver of the inpout32.dll Logix4U which is included in VB.NET program listings I provided.

The picture on the right side is an excerpt of the program. If the ON button is pressed, then the electrical equipment connected to the LPT-AC220V module will light. To turn it off, it can be compressed OFF button.

Simply put, electrical appliances can be turned on by sending data 255 (decimal) or FF (hex) or 1111 to 1111 (binary) to the parallel port. And to turn off electrical equipment, then the program sends data 0.

LPT-4DCM - DC Motor Control 4 Fruit Of LPT (Parallel Port)

 

 

Controlling the 4 pieces of small DC motors (max 600mA) now you can do easily from your computer using LPT parallel port interface. All you need is the LPT module-4DCM.

As shown by the photographs in addition, the module can control the LPT-4DCM 4 pieces of small DC motors. Controls include clock-wised Rotation (CW), Counter-Clock Wised Rotation (CCW), and STOP.

LPT-4DCM module uses 2 IC L293 each used to drive a DC motor with 2 pieces of maximum current 600mA - 1.2 A. With this module, you can easily drive the motor and controlling the direction of motor rotation with a computer programming language that you know well.

 

If you buy-4DCM LPT module, then you will get 1 unit motor driver + 4 small pieces as a complement. And also a CD that contains the installer Editioin VB.NET Express 2005 with a sample program using the motor control applications-4DCM LPT module complete with source-code and library inpout32.
