Maxim Integrated give a walkthrough for their MAXREFDES89, a brushed DC motor controller Arduino-compatible shield:
What could you build with a brushed DC motor controller Arduino® shield? Our Arduino-compatible brushed DC motor driver reference design drives up to four motors, and easily interfaces to an mbed® platform. Featuring MAX14871, 4.5V to 36V full-bridge DC motor driver, MAXREFDES89 can be used with a wide range of motors, from mid-voltage down to battery powered.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
