Has anyone used several of these sensors together? I have to design an array of ultrasonic sensors for an obstacle detection system for drones.
Also is it possible to use the analog pins on an Arduino for the Trig signal when using them in mode 1? Reason for this is I need 8 sensors wired up to 1 Arduino Uno (not enough digital IO pins for the 16 connections needed), or can I simply connect several of the trig wires to one digital pin?
Thanks in advance.
