can anybody tell me how to interface an ultrasonic range sensor with bolt device??
that is totally incorrect it doesn't work. I suggest you should first check out how the sensor works
I believe you will not be able to connect it directly with Bolt. You can interface an Arduino in series and use Bolt to update the data to cloud. Check out http://www.instructables.com/id/Washman-the-Washingmachine-Monitoring-System/ . This may help.
Thanks for the info. I commented a disclaimer unto the original post.
