Information about the 28BYJ-48 stepper motor and ULN2003 driver board. The 28BYJ-48 is one of the cheapest stepper motors you can find.Although it is not super accurate or powerful, it is a great motor to use for smaller projects or if you just want to learn about stepper motors. Mar 24, 2015  Stepper Motor 28BYJ48, ULN2003 driver board and Arduino Library Jan 11, 2013, 03:59 am Hi, I and very interested in Arduino and now trying to understand a small stepper motor. Connecting the 28BYJ-48 stepper motor to the ULN2003 driver board. Usually, the 28BYJ-48 stepper motor comes with a 5-pin connector that will fit to the ULN2003 driver board. Connecting the ULN2003 driver board to the Arduino. Connect the ULN2003 driver lN1, lN2, lN3, lN4 to the Arduino digital pins 8, 9, 10, and 11 respectively.

Wiring the ULN2003 stepper motor driver to Arduino Uno. The ULN2003 stepper motor driver board allows you to easily control the 28BYJ-48 stepper motor from a microcontroller, like the Arduino Uno. One side of the board side has a 5 wire socket where the cable from the stepper motor hooks up and 4 LEDs to indicate which coil is currently powered. Information about the L298N Motor Driver. The L298N Motor Driver Board is built around the L298 dual full-bridge driver, made by STMicroelectronics. With this motor driver you can control DC motors, stepper motors, relays and solenoids. It comes with two separate channels, called A and B, that you can use to drive 2 DC motors, or 1 stepper motor when combined.

I had acquired some Stepper Motors from Ebay, that didn't work well with the Adafruit Motor Shield. Looking at the specs the problem here was the resistance/current/voltage rating;

Rated Current/phase2.0A

Phase Resistance1.4ohms

Power2Go supports all formats of disk format in the market.

Voltage2.8V

So, for Stepper motors, the resistance per phase is a constant. The Rated current is the MAXIMUM current the motor will take before bad things happen, and the voltage is the calculated voltage that will give a constant current at the rated current, for the motors resistance (V = I x R, V = 2.0A x 1.4Ohm = 2.8V).

The Adafruit stepper motor shield cant supply 2A,and has trouble with voltages below about 5V, so couldn't properly run my motors (they jittered but didn't smoothly move).

So, I got some stepsticks and decided to wire them up to my Arduino.

Other Materials

For this I also used;

An Arduino Uno, but any Arduino compatible should do

A Stepstick, or compatible stepper driver using a A4988 or DRV8825

A 12V power supply

A breadboard

Some hookup wire, I used solid Cat5 strands.

I also used a couple of LEDs and some 220Ohm resistors
