This Project uses a 9dof Sensor Fusion to Locate the real Northpole with 2 ESp32 (1 to Drive the stepper and the Second to connect via BLE as Locator).
The 9dof Sensor is straight mounted to the Stepper Motor Backplate., so you can measure the Real Azimuth and Elevation for Polaris. (Implementing Calculations for GPS Position and Real Time) The Handyholder mounted on a Polaris Aligned to the drive Shaft does automatically Follow the Stars with Earth Rotation Speed.
The Display shows up a Target Crosshair to Catch exact Polaris during its Position is outer View (Real Northpole never Change directly)
