      Perhaps you should debounce the button since mechanical buttons can produce many pulses when pressed. One of the simplest methods is to connect a tiny capacitor in parallel to the button, which, along with the pull resistor, creates a low pass filter.

      Perhaps you should debounce the button since mechanical buttons can produce many pulses when pressed.

      One of the simplest methods is to connect a tiny capacitor in parallel to the button, which, along with the pull resistor, creates a low pass filter. To press that button, the time constant of that filter needs to be a little bit less than the duration of the maximum speed (e.g. 100..200ms).
