    Hi there, this is probably a question that has been answered many times before, but I'm new to computer interfacing with electronics.
    What I want to do is control a bank of relays with a USB port.
    Ideally I'd be able to write a program to send data to this.
    Does anyone know of such a board, as the main issue is that it has to work immediately. As in once I click a button on my PC I need the relay to react, not have to wait for the program to be uploaded again.
    Thanks in advance, Daniel.
