Lastly, a single DC power supply can be used for the Arduino and motors, after that the shield will handle the rest to ensure your servos and motors will operate properly. Secondly, we can also set motors' speed and define maximum speed by software using the Adafruit Motor Shield library. When to use Arduino Motor Shield L293D?įirstly, we can save some space on the robot chassis, plus much fewer jumpers are used for wiring up when using the Motor Shield compared to the L298N Motor Driver. That being said, let's have a quick look at the comparison below to choose the best fit.ġ. In this project, I'm going to walk you through how to make a simple Arduino Flinching Robot step by step for those who prefer the L298N H-bridge Motor Driver to the Motor Shield.īefore we get started, have you ever wondered whether to choose an Arduino Motor Shield or an L298N Motor Driver for your project? I personally prefer the L298N Motor Driver because we can then use more of our Arduino's pins to add some more functions to our robot!
