Arduino – 5 Ways to Power Up your Arduino


This blog post will give you show you 5 different ways that you can power your Arduino board.

5 Ways to Power Up your Arduino

  • USB: that’s probably the most common way people try their projects. By simply plugin your Arduino board into your computer through an USB cable it will power up your Arduino.


  • Batteries: You can use two different types of batteries:
    • Disposable batteries: One of the most common ways is to power up an Arduino with a 9V battery, just like the image below shows. Keep in mind that those batteries are a bit limited, so your Arduino won’t be able to supply many sensors or motors.


    • Re-charged batteries: Those are simply battery cells that you can recharge. Are a great solution for robotics.


  • Wall-Warts ( those supplies simple produce low DC voltages from high AC voltages): You must be careful when you’re using a wall-wart because sometimes they produce much more voltage than the actually power supply says in the label. And the voltage regulator on your Arduino won’t be able to handle so much voltage.


  • Solar Panel: When It comes to choose a solar panel to power up your Arduino Projects you must be careful. Photo voltaic solar panels comes in different sizes, prices and some my give you a higher voltage or a higher current. So before you choose one, keep in mind what’s your project for and what it needs.

Where to get all those power supplies from? I choose amazon.com.
