Hi, i am attempting to connect "3" sets of beam sensors to arduino motor shield which is suppose to send a signal to a relay switch to turn on/off a motor. There will be various sequences of "on and off" based on the sensor's reading. I am very new to all of this so my question is - where do the pins get connected to on the board - i am thinking digital pin area. And how would i connect the relay to the board. Any assistance is greatly appreciated.
