6. Customizing the ShieldThis motor driver shield has several features that will not be useful in a typical application but that might benefit anadvan

In all cases, the top through-hole of the pair connects to the Arduino pin and the bottom through-hole connects to themotor driver pin. To change one

only ENA/DIAGA will have the required pull-up resistor; you will need to add a separate pull-up resistor for theENB/DIAGB pin, or connect it to a micr
