     * sketch did not work with ESP8266 (Wemos D1 mini) -> I had not used the pin for "​direction"​ yet; it defaulted to "​8";​ this interferred with pin "​D3"​ for "​step"​ -> changing the direction pin away from 8 solved the issue (that was a tricky one; the sketch worked perfectly on my Arduino Uno; so the only - apparent - changes were the Board (Arduino Uno -> Wemos D1 mini) and the pin (9 -> D3)     * sketch did not work with ESP8266 (Wemos D1 mini) -> I had not used the pin for "​direction"​ yet; it defaulted to "​8";​ this interferred with pin "​D3"​ for "​step"​ -> changing the direction pin away from 8 solved the issue (that was a tricky one; the sketch worked perfectly on my Arduino Uno; so the only - apparent - changes were the Board (Arduino Uno -> Wemos D1 mini) and the pin (9 -> D3)
 +    * setup appeared to be very sensitive to touch; even getting near the A4988 controller board seemed to cause the stepper to stop rotating and instead vibrating very strongly
