I am using Nodemcu Devkit v1.0, programmed through the Arduino IDE. I am trying to drive 28Byj-48 motors through ULN2003 drivers. Whenever I try to make the motors spin, they just vibrate. I do not have my wires crossed as I've tried every permutation of the wires. Any ideas what could be causing the problem?

Hi, what voltage and code are you using? If it's 5V or above and your not trying to move them to quickly it,s most likley the wiring.

Try using PWM capable pins for driving the ULN chip.
