I am very new and this is my first project outside silly exercises and the intro kit book, so take it easy on me.
I am trying to make 4 servos dance when (and only when) I hit 1 on my 16 key touchpad (as a precursor to using these elements to turn my garden hoses on and off... baby steps here). They are supposed to dance once each, then stop until a button is pushed again.
However, when I upload the code below, the servos dance without any buttons being pushed. Furthermore, they continue dancing in sequence on a loop despite my loop ending with converting my variable lastPush to a non-1 number. I cannot determine what I am doing wrong. I barely understand libraries yet, and I am using 2 of them, so I suspect the issue lies there somehow. I am sure there are a number of other unnecessary or incorrect things I am doing as a result, so if you see something, feel free to mention it.
Thank you for any help you can give. I am really enjoying this hobby so far.
