How to use an external hardware button trigger an event in windows
Posted on 2007-11-28
i have a physical, hardware button mounted on the outside of our business, next to our front door. is there any way i can connect it to a windows computer so that every time it is pressed it appends the date and time to a text file? i can do all the programming either via batch file or visual basic but i do not know where to start interfacing a physical switch to a windows computer. is there some way to do it via serial, usb, parallel? any help would be great. thanks!
