Connect the ULN driver lN1, lN2, lN3, lN4 to the Arduino digital pins 8, 9, 10, and 11 respectively. The driver board has two pins which are labeled GND and VCC, which are two pins for the power supply. The ULN driver board’s GND pin must be connected to the Arduino’s GND pin. Similarly, the driver board’s VCC pin should . The driver board requires power. Make sure your power supply has sufficient power to drive the stepper motor. It is usually a good idea to use a separate power source to the one that is driving the microcontroller. Having wired a GPIO pins to the driver board you can test the interface. Set the GPIO pin high and the corresponding LED on the driver board will illuminate. Set it low and the LED turns .

ULN Stepper Motor Driver Features. We usually use stepper motors when we need precise control of the motor shaft. These motors can be used in robot arm, 3D printers, CNC machines, etc. 28BJY is a kind of stepper motor. In full step mode, these motors have a 1 to 64 speed reduction gearbox and eachfull degree rotation consists of 32 steps. Connecting the ULN driver board to the Arduino. Connect the ULN driver lN1, lN2, lN3, lN4 to the Arduino digital pins 8, 9, 10, and 11 respectively. The driver board has two pins which are labeled GND and VCC, which are two pins for the power supply. The ULN driver board’s GND pin must be connected to the Arduino’s GND pin. Similarly, the driver board’s VCC pin should be connected to the Arduino’s 5V pin. Once again we will use the separate 5V power supply to supply power to the ULN driver board. Now connect the second driver board’s IN1, IN2, IN3, IN4 to the Arduino digital pins 4, 5, 6, and 7 respectively. The following illustration shows the wiring.

This is ULN Driver Module Stepper Motor Driver, small size and easy to use. It uses the ULN driver chip to amplify the control signal from the. We usually use stepper motors when we need precise control of the motor shaft. These motors can be used in robot arm, 3D printers, CNC machines, etc. The motor usually comes with a ULN based driver board. The ULN is one of the most common motor driver.
