So, I'm back to another tutorial! Well, today I'll show how to correctly use external power supply with Arduino!Is Really simple, You will see:<h3 >Power supplies</h3>Well, power supplies are used for every projects with Arduinos, like controlling Leds, Servo motors, Relays and more!But sometimes, The Arduino can't be a power supply because of the project, like controlling more than 1 servo motor with the only 5v of the Arduino.This example shows:<figure><img src=https://projects.arduinocontent.cc/20253b54-bb4d-4be3-8a58-7a0e08d3a338.png /><figcaption>the example</figcaption></figure>So, this example shows that isn't possible to control 5 servo motors with Arduino as power supply, so what's our solution?<figure><img src=https://projects.arduinocontent.cc/3a5d1fa8-957c-41cc-a3d6-1a38bf84416a.jpeg /><figcaption>Think a bit more</figcaption></figure>The SolutionYes! The solution is very simple, but you need to take care to not doing anything wrong.So, our solution is using Batteries as external power supply!Some external power supply examples images:<figure><img src=https://projects.arduinocontent.cc/119abc4b-8a1d-4ccf-b4a2-7b164c6786b0.jpeg /><figcaption>Computer power supply</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/1052ce03-bbfc-4e7d-b3ee-a9fc064f939c.jpeg /><figcaption>Table Power Supply</figcaption></figure><figure><img src=https://projects.arduinocontent.cc/1c094469-0c14-4357-8a34-cf0960120809.png /><figcaption>Batteries </figcaption></figure>Well, there are some examples, but, how to use correctly them?Check the Schematics!
