Can we recieve data from hardware and display it on our computer screen through VB? Like we connect 5 switches with parellel port. When we press first button it displays on computer screen that first button is pressed.
Thanks a lot for the info! I've finally got around to try it, and it works great. I controlled a simple 5V relay with it, so the lpt port couldn't take that load. But I connected the power supply of the computer to +5V, and a transistor to control that. It worked like a charm! The relay controlled a motor. Fun stuff.
Thanks again! It's great to see that not all youtube comments are braindead :)
Crap, I forgot to mention. Make sure that you connect the ground pin on the parallel port to the ground in your circuit. This is very important. As well, if you want an easy way of testing, enter in the the dos prompt, then type "debug", then type o378 **. Stars signify a hex number. Use data pin#1 and type o378 01. This will turn data bit#1 on, and keep the other ones off.
can we interface LDR with Parallel port ?? or can we receive data throught parallel port ?
