About this product
The ULN2003 is a 7-channel Darlington sink driver array that lets a low-power logic signal switch higher-current loads such as relays, solenoids, lamps and unipolar stepper motors. Each channel includes an internal clamp diode for inductive loads, and its inputs are compatible with TTL and CMOS outputs.

How do I connect the ULN2003 to a unipolar stepper motor?
Connect IN1 to IN4 to four microcontroller pins, the matching OUT pins to the motor coil wires, and the COM pin to the positive motor supply. Drive the inputs in the correct stepping sequence in your firmware.
Can the ULN2003 switch a 12 V relay?
Yes, as long as the relay coil current stays within the 500 mA per channel limit. Connect the relay between the 12 V supply and the channel output, and connect COM to 12 V so the internal clamp diode protects against coil back-EMF.
