You did mention that it isn’t easy! I did download PlatformIO and found it to be just as foreign to me, so instead of confusing myself with two different applications I figured I’d stick with the Arduino IDE for now. I just went through and deleted what I thought was my duplicate library, other than that I’m not sure what libraries might be missing as I’ve tried to follow the directions as closely as I could. I’ve attached the sketch. Thanks for taking the time to help me.
