Hi,
I am currently building a project for a prototype using ultrasonic sensors. I have however, a few questions:
-
What is the maximum number of sensors I could attach to a single board considering each one needs two digital pins, as well as ground and 5V. I've been looking at the Mega EV3 with 54 digital pins but I am unsure whether it would cope with 27 sensors attached.
-
How close can each individual sensors be before they start to effect each other/ will they effect each other when close together?
Any advice is much appreciated. Thanks,
George
