Re: Remote pump control ideas.
Ok, there were two posts there, but I sorted out the first one - the one about the pin numbers (no delete option here unfortunately, since I would've removed that one).
I sort-of worked out the second issue too: again, I checked all my connections and wiggled them around (I'm currently on breadboards) and it now works better - the LED no longer dims in sync with the buzzer, though I'm STILL a bit surprised that a "HIGH" pin only reads 3.3v. Having used Arduino so far, I was expecting 5v...
