Stepper motor set with motor and driver

This unipolar stepper motor set with driver is perfect for small craft projects with motors. The stepper motor can be easily connected to a stepper motor driver module via a plug connection. The stepper motor has a gearbox with a ratio of 1:64 this ratio has a certain deviation. If the motor is always turned in the same direction, for example in a clock, an error can occur. This error can be compensated for if the position is determined sporadically with a light barrier module. This also has the advantage that the start position can be determined exactly when the stepper motor is switched on for the first time.

ULN2003 driver:

This stepper motor driver module with a ULN2003 (Darlington transistors) SMD chip is perfect for the 28BYJ-48 stepper motors. Since the module has the same plug as the 28BYJ-48 stepper motor, it can be plugged in directly. The module also has four status LEDs. These serve to visualize the controlled outputs (windings of the motor). Since the power supply is directly looped through, this board is only suitable for small stepper motors. For control, you will find a suitable library in the library manager under "Stepper".
