No sensory input on a motor shield?? Answered

Hello, I recently acquired a seeed motor shield


But what i notice now is that there is nowhere to attach my Sr04 ultrasonic sensor! How do I include sensory input on my robot with this shield? Thanks bunches.

You need to find out what pins, if any, are not being used by the shield. Then get yourself a proto shield. This will go between the arduino and your motor shield and allow you to wire in whatever other sensors you need to the unused pins of the arduino.

If there are no unused pins then you may want to upgrade to an Arduino Mega.
