VB.NET Program to send Voltage signal in milliseconds
Posted on 2012-09-02
I am currently needing to write a VB.NET program that will do the following:
-- I need it to send a 4mA signal at 80 milliseconds
-- I need it to send a 20 mA signal at 180 milliseconds
I would like to do this in VB.NET as it is language I am most familiar with, which isn't saying a whole lot :).
I am thinking if it is possible to just send the different voltage amounts out the USB port, which has up to 500mA of power?
I hope that is enough information. I am just seeking the best way to do this, it doesn't have to be USB or a program, but just need a way to send those two signal voltages at that speed.
Thank you for you help and thoughts!!
