Hello everyone,
I was wondering if it was possible to send basic keyboard input to my PC from my Gadgeteer hardware. For example, if I moved the joystick right, would it be possible to simulate a right-arrow key press on the computer? I very much doubt it, but any information would be great. Thanks!
Yes you can. Take a look at USB client tutorial.
Ok.
I read the tutorial, but I’m getting the InvalidOperationException error. Would this work with the USB transport setting in any way, or do I have to use serial? The reason I ask is that the device I’ve made does other things as well as trying to simulate the keyboard, and I wanted that to be an extra rather than the only thing it does.
Thanks for your help!
Of course it will not work, as explained in the tutorial 
If USB is used for something (debugging) then it can’t be used for other things (keyboard)
