I was really confused about how many sensors (Arduino ultrasonic sensors) and vibrating motors (mini disk motors) can be attached to an Arduino r3? We have about 28 ultrasonic sensors and 28 vibrating motors to connect.
What confused you? Do you know how to connect one sensor? Do you know how to connect one motor? I would start there. Once you figure that out, it should be trivial to count up the pins you have and figure out how many of each you can fit.
By the way: It is really really exceedingly terribly horribly stupid to put your phone number out on the internet in a place like this. You're inviting abuse from some rather unsavory characters. I would strongly advise you to edit your post and remove that.
