stepper control mqtt

i want to program a node mcu connected to mqtt and stepper motor 28byj-48 uln 2003 with arduino ide and control it with a slider bar from node-red dashboard To control the curtain of the room so that the slider is between 0 and 100, the exact position of the curtain can be adjusted. The number of steps to open or close the curtain is 8260 steps. please help me

smaeel take a look on the standard range node from the palette, like this you can easy scale from one range to another.

As starting point of course, you will need a counter a matrix etc...
