Pancho is a little rover controlled via Bluetooth using iShield App for iOS devices. It also uses a Blend Micro compatible with Arduino, it's very easy to build and the code is very simple.
I'm using a 3D printed rover you get at Tindie. This rover comes with a trinket pro but for this project we are going to use the Blend micro. Also it uses a continuous rotation micro servo which have 3 terminals: GND, Vcc and signal. Vcc and GND are connected to the batteries and signal is connected to a pin from the Blend micro.
Remember to download iShield from the App Store to controll the Rover.
