#96284 There is a ton of examples how to make this stepper motor with ul2003 driver to operate using esp8266 but my motor never moves.

I have tried to use USB charger as a power source as well as an external HDD 12V power source as well as an external charging station as a power source for the motor.

When i connect the signaling cables 1-4 to the nodemcu pins, the 5V voltage on the driver goes to 3.3V
When the motor is disconnected the leds flash in sequence as i would expect them to flash when the motor was moving

Any ideas what could be wrong with the setup and how to make the stepper motor to turn? ... 8-uln2003/ this is the setup i am trying but it does not work
