Hello all, first off, I apologize if this topic is already out there, I could not find one discussing a similar issue.
I'm a new Arduino tinkerer and enjoy it a ton, but my knowledge level is extremely low. A big thank you to all of the wonderful people out there who upload their sketches and allow us to tweak them as we see fit! I'd be absolutely lost without you.
I have a sketch that runs great when using UNO but when I try to compile and upload the same sketch onto Nano 33 BLE Sense, I get the following error - invalid conversion from 'const char' to 'int' [-fpermissive] inBuffer = "";*
Here is the code (I'm sure it can be improved upon a lot) :

AccelStepper stepperY(1, 4, 5); //Sets up the pins for stepper Y

I'm sure there are better methods that will achieve what this code does, maybe one day I'll figure that out.
Is there something that must be converted to be able to run this on NANO 33 BLE Sense?
Any help would be great!
