Hello,
I am making a robot crossing guard. When the robot senses motion (PIR sensor), it will play a low note on the piezo buzzer, and light up a red LED light. My PIR sensor runs on 5v. And the motors run on 6v. My problem is I already have jumpers and input cables plugged into the Arduino. And for the motor shield to operate, I need ALL the pins on the Arduino available. My dad says only some of them are needed for the motors to operate to power 2 motors, so he bought special Seeed cables. How can I do this?
Seeed Motor Shield:
(Message me if you want to see source code)
Thanks,
Mac
