This can be done by passing the current and target positions to a function which can calculate a bearing. The calculation for this is approximated by the following formula asen-USTelligent Community 12https://community.element14.com/members-area/personalblogs/b/andy-clark-s-blog/posts/azure-sphere-secure-iot---connecting-to-azure-functionsWed, 14 Nov 2018 20:31:11 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4a5edae0-3ca8-4e41-b3e4-f4474a419e22DAB1<p>Interesting capability.</p><p>I am not sure if I am ready to start poking Azure with a stick yet.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=5891&AppID=312&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/members-area/personalblogs/b/andy-clark-s-blog/posts/azure-sphere-secure-iot---connecting-to-azure-functionsWed, 14 Nov 2018 09:45:39 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4a5edae0-3ca8-4e41-b3e4-f4474a419e22Fred271<p>I&#39;m following your investigation of Azure Sphere with interest.</p><p>&nbsp;</p><p>A couple of comments on the project in general though.</p><ol><li>How are you going to zero the stepper motor when it&#39;s powered on? When I did a similar project many years ago I used a servo that had been geared to rotate more than 360 degrees. Obviously this would sometimes require a complete sweep around as it couldn&#39;t continuously rotate, but meant I had no problems knowing which way whether I was pointing to one side of the box or the other.</li><li>Why not calculate distance to your target too?
