so how can I build the circuit?

yes in different directions for calculate volume into a deposit with the same breadboard

my difficult is that when I copy the circuit in a specular way I can put only 2 sensor on a breadboard...I don't know how put the 3th sensor there

I thought to reply this one but i have 1 breadboard and i would use it for connect each 3 sensors because i have no time to buy another one and I have a competition about IoT for find a new job

ok thanks can i know how connect the other 2 ultrasonic if the first one it's connected in this way http://www.raspberrypi-spy.co.uk/2012/1 ... on-part-1/
I'm not expert so i want calculate the volume with python

l'ho collegato seguendo le indicazioni sul sito, mi sarebbe utile riuscirne a collegare altri 2 sulla stessa breadboard

Hello,
i want know please how many ultrasonic can I add to a raspberry pi model b, i added one as is written on the tutorial on the official website and everything ok, but i want add other 2 for calculate volume. Thank you!

Buongiorno a tutti,
vorrei sapere quanti sensori ultrasonici si possono collegare ad una raspberry pi model b, uno l'ho connesso e tutto ok ma ne vorrei connettere altri 2, grazie!
