I am in the middle of building an ROV and there is one feature I would like to add.
I have a GY-273 3 axis magnetometer module that I would like to use to sense ferrous metal, ideally I would want the data as a changing tone perhaps via a VCO.
This would be used to help find and retrieve lost anchor chains for our sailing club amongst the other things it will do.
At the moment I have a 18m2 doing most of the control functions and sounder, so would use another picaxe for this job.
Most of the information and data refers mainly for what it is designed for, a compass.
I do not require and graphic or digital O/p, just a tonal change associated to the magnetic changes.
Any help out there to at least get a varying voltage of digital range from the module via the Picaxe which I may then work on.
Thanks in anticipation
