I'm looking for a way to control the output voltage on a USB cable through programming. I don't know too much about how to program USB devices, but I know there's a default 5v output, a ground, and two data lines in every USB cable. Ideally, I would like to be able to set this voltage output to...
Hello, I'm trying to convert a simple 5v DC source to AC using the simplest method possible. The project I'm trying to do involves a 4-bit counter that requires a clocked source, so I need to be able to specify the frequency. Is this possible or can anyone help?
