Wiring the L298N module to control a DC motor, with an important safety note on the 5V jumper when exceeding 12V.
Wiring the L298N module to control a bipolar stepper motor like the NEMA 17, and comparing it to the L293D chip.
Wiring the L293D chip to control a DC motor's direction and speed via direction logic and pulse-width modulation.
Wiring the L293D chip to control a stepper motor via four direction pins and the Stepper library, with the difference between unipolar and bipolar motors.
