my 1602 lcd keypad shield have "D1 ROBOT" markings. when you say "visually inspecting" it, does it translate to my shield and/or uno board getting fried?i let it run for more than 30 minutes already using analogWrite and it appears okay to me.i'm into software and noob in arduino

It amazing how many of these companies producing products don't have anyone with the technical expertise to know how to properly control a transistor. That seems like some pretty basic EE 101 knowledge.Even worse, doing it correctly does not affect the product's manufacturing costs.
