The video shown here demonstrates control in both directions of both continuous and discrete steps. Utilizing both the AdaFruit Stepper Motor Hat along with the motorHat python library, the stepper motor is able to be controlled with a single command. This allows the motor control to be light weight and fit into the larger detection loop.

Subsystem 2 Alpha testing
Subsystem 2 consists of the RF detection and deterrence systems. In the Alpha testing stage of this subsystem, the team is able to view the RF spectrum about the center frequency of the Drone's control signal in order to predict where in the window communication is occurring if a drone is present. In the future this system will be awoken by SS1 in order to conserve on power and system resources.

The following video shows the live Drone control spectrum in the top right highlighted in white. The code shown is a detection algorithm that tests the spectrum for Drone control signals and displays its best guess at where the drone communication window is at that time window. This positively demonstrates SS2's ability to detect a drone through RF interpolation.
