Relay dropping out momentarily
Just playing with my brain, I have a relay hooked up to the brain, nothing else other than 12v power and the USB. The relay drops out momentarily every few seconds. It's inconsistent, and just clicks as it drops out and pulls back in before it drops all the way out. The 12v centre positive transformer is rated at 2A so I know that i'm not short on power to hold the relay in. The LED beside the output port flickers as it loses voltage and reenergizes instantly. This random clicking is driving me crazy!
I've now tried this with multiple relays, and even a better faster computer, still have the same problem.
As far as how I'm setting it up I went through the ninja kitty wizard of doom with the default template to make the setup as quick and painless as possible so there's really nothing complex or extra going on. I have no inputs hooked up at the moment.
