Under Hardware & Software Needed, it says I'll need an Arduino UNO (got it) and Arduino Motor Shield Rev3 (got it). It also says that I will need a DC motor (6-12V) and a Power source.
Could someone provide links to the specific DC motor and Power Source I need to buy. I'd buying all this in US.
@LarryD Thank you. The tutorial states that 2 batteries should be used. Should I buy a holder for 2 batteries (like this) or the 8 battery holder you linked to will be fine?
