Here is what all you will need:
Follow the circuit diagram(click on it to get full view) and start by plugging on the 555 timer IC and the motor driver on the breadboard.
Then, continue by connecting the capacitor and resistors to the 555 timer IC. Check the images above for reference.
Connect the two pairs of the stepper motor's wires to the outputs of the A4988 driver board. Connect 1A and 1B to the first pair and 2A and 2B to the second one.
