Hi, im making a project where i input a value and the arduino moves a stepper motor to that location. I'm using a 16x2 LCD for output, and want to add a 4x4 matrix keypad to enter the value instead of in the serial monitor. However, no matter how i try to implement it, it always results in an error. …

makes sense as the distance to go is 0 so you get the message repeated. We need a boolean variable to only display that once. (I added moveComplete that is set to true or false based on activity) try this #include <Keypad.h> #include <AccelStepper.h> #include <LiquidCrystal_I2C.h> LiquidCrystal_I…
