ULN2003 Description
The ULN2003 is a Darlington transistor array chip used for connecting high-current electrical devices to microcontrollers, suitable for driving relays, stepper motors, LED arrays, logic level conversion, and other applications.
28BYJ-48 ULN2003 Schematic Diagram
To connect the 28BYJ-48 to the ULN2003, insert the 28BYJ-48’s 5-pin terminal wire into the ULN2003’s 5-pin socket. Then connect the ULN2003’s IN1, IN2, IN3, and IN4 to the control pins respectively. Finally, connect the positive wire to the 5V power supply and the negative wire to GND for operation.
