Avoid overworking pins due to excessive current – to put things into perspective, a hobbyist HCROBO0061 5V DC motor needs 55mA to spin.This can break the output pin you’re using for the motor. Prevent damage through counter EMF – counter EMF happens when you turn the motors backward which induces an electromagnetic force that’s so strong that it starts reversing the flow of electricity from GND to the output pin.Here’s a big warning – don’t you EVER try and put a DC motor directly on your Arduino’s pins, or any other microcontroller’s pins.

In fact, you could run four DC motors over a single L293D motor driver shield for the Uno. Good to know: If you’re planning to choose an ESP32 over an Arduino Uno, remember that there are Arduino shields that can give the latter more functionality. Power interruptions are no issue – an Arduino board can be abruptly cut off from power again and again, and it’ll still work like normal.Power constraints – if you are running on limited power through a battery or power station, you can run an Arduino on less power than a Raspberry Pi.Lower cost – you can buy more Arduino boards to drive more DC motors at a lower price.But here are three reasons why you might want to choose the latter: A lot can be said about the differences between a Raspberry Pi and an Arduino.
