I have a differential drive project I made from recycled Powerwheel units. I was using R/C equipment with aSabertooth 2X25 to test / design it.I would like to install an Uno with GPS shield and a bluetooth shield that would communicate with my cell phone to allow the vehicle to follow me as I walk my property. I have seen similar projects that uses a compass along with the GPS to follow a predetermined course. Would a compass be necessary in my project?
I have found that GPS signal has no way of interpreting orientation.
Strange. Mine has no problem at all telling which way I am going.
