Arduino

I am looking to buy the parts my son needs to make an arduino blue-tooth robot. I have in my cart the Arduino basic kit, motor shield, stacking headers, a 9volt battery pack, and metal casters ( I bought gear motors/wheels and ultrasonic range sensor ); but I’m not sure what blue-tooth module I need to work with an android phone.

Thanks
Andrew

Hi,

The DFRobot Serial Bluetooth Module would normally work.
Please note that we offer this DFRobotShop Rover V2 - Arduino Compatible Tracked Robot (Bluetooth Kit) that might interest you.
Here is a blog post to control the DFRobotShop Rover through Bluetooth with an Android App.
