There was an interesting share in our SDC Nano Degree Bangalore Whatsapp group. I wanted to try out something similar based on the stuff I had with me. The intent is to map room using ultrasonic sensor and stepper motor
The project is forked from Param’s Project https://github.com/paramaggarwal/pingray that uses ultrasonic sensors and magnetic compass. It is a curious attempt to replicate the outcomes with a stepper motor and single ultrasonic sensor as I did not have a magnetic compass.
All limitations metioned in Param’s post (https://www.hackster.io/paramaggarwal/mapping-a-room-with-ultrasonic-distance-sensors-9725b7) apply. Additionally this project can only capture 180 deg.
