Maybe you should ask Radio Shack for the documentation. They took your money. They should provide documentation.
So Arduino is responsible and they should have documentation for their products
but it dose not have example code do drive a dc moter
QuoteSo Arduino is responsible and they should have documentation for their productsYou mean like this:http://arduino.cc/en/Main/ArduinoMotorShieldR3What example code do you need?
Radio Shack take note, hire technically competent people if your are going to serve the electronics hobby market.
It is amazing that radio shack still carrys any electronic hobby parts.
