L298 and unipolar motor

[jimbo.we]

Yes but the motor is driven as a bipolar ( with the half coil disconnected ), is a common solution to use with 6 wires unipolar motor and should work.

I’ve loaded on the seeduino the tutorial sketch founded here: arduino.cc/en/Tutorial/StepperBipolar but all I get is just a sort of motor vibration.

I’m sure I’m doing something wrong with the connections, the documentation for the l298 driver is not very clear: for example the documentation say only “EA is connecting with PWM port of control board to control the speed of motor” but is only for DC motor or I still need to provide a pwm signal also for the stepper?

Yes, EA and EB need to be connected to +5V/set to HIGH.
