In this article we are going to show you the 10 Most Useful Arduino Shields. This is our opinion based on the many shields that we have tried and tested.If you are new to the arduino platform then you will quickly realise that shields are a quick, easy and usually low cost way to easily add functionality to your arduino. Rather than building circuits on breadboards or designing prototyping boards you can simply attach a shield and get the functionality
