I am planning on buying arduino motor shield (A000079 Motor Shield Interface) but before I buy it I had a few questions. I am planning on building a wifi controlled car. I am planning on stacking a wifi shield on top of the Arduino uno r3 then stack the motor shield on top the wifi shield. Questions:
Can I attach a ultrasonic sensor, 5 volt servo motor, and stepper motor to the motor shield?
I know you can attach sensor to the Arduino Uno and wifi sheild. So I was wondering does the motor shield have the same pins as arduino uno and wifi shield?
Do I need to attach a battery to the motor shield to control a stepper motor?
