The 28BYJ-48 Stepper Motor and ULN2003A Driver Board is a low-cost motor set that is widely used in projects requiring precise motion control. The stepper motor provides high accuracy in robotic arms, automatic shutter systems or rotary mechanisms because it moves by dividing a full revolution into specific steps. The ULN2003A driver board amplifies the low-current signals from the microcontroller to safely transfer the power required by the motor and allows you to visually monitor which phase is active thanks to the LEDs on it.
