I need help developing a prototype for an ultrasonic sensor used for obstacle detection. I'm currently lost and could use any help anyone could provide. What supplies do i need, how do i assemble it, and where can i get these supplies? If you could give me any assistance it would be greatly appreciated. Thanks.
