Hi,
I just picked up a TinkerKit DMX shield for my Uno. I've connected three wires from the "output" terminals, uploaded the example FadeUp sketch, and watched as nothing happens.
I'm new to the shield and DMX, but I've successfully sent commands from another device to my DMX driver, and it's network address is 1. I'm hoping I'm overlooking something simple, like the wrong number of max channels, or missing a jumper, or something. Does anyone with experience know a few basic places to start troubleshooting?
Thanks
Edit: Pro-tip: make sure that the driver still works before you troubleshoot. Thanks for all the help.
