    Get All the Stuff!

    Here is what you will need:

    • An A4988 stepper motor driver
    • 2 555 timer ICs
    • A prototype breadboard
    • A 12-volt power supply
    • A 5-volt power supply(Conversely, you can also use a voltage regulator with 5-volt output such as an LC805CV)
    • A 1kΩ resistor
    • 2 10kΩ resistors
    • 3 LEDs(Optional)
    • 3 330Ω resistors(Optional, for the LEDs)
    • A capacitor(0.3uF to 10uF, try experimenting with different capacitors in this range. Capacitors above this range will cause the stepper motor to move very slowly and ones below the range will not allow the motor to move at all. Make sure the capacitors are rated for voltages above 10 volts.)
    • A 100kΩ potentiometer
    • 2 push-buttons(normally open ones)
    • A lot of male to male jumper wires
  • 2
    Start by Plugging on the A4988 Motor Driver on the Breadboard

    After plugging on the motor driver, connect the VDD(or VCC) pin to +5vols, GND to, obviously GND and, VMOT to 12 volts. Don't forget to connect the SLP and RST pins together! I used a small jumper for that.

    Please note:- For the IC(1), the pin6 needs to be connected to pin 2 of the chip.

    Please move to the next step before starting making the circuit.
