IMPLEMENTATION

Installed Raspbian headless on the PI and rpi-mjpg-streamer. The previous Rover used a Netduino3 with WIFI. The Raspberry PI now formed the primary unit connected to WIFI with a Serial port connection to a Netduino2 that contained the MotionTrap logic. I also added a light. First problem was getting the Netduino to work on my pc which had had several updates. I needed to install a new version of the dotnetMicroframework, the Netduino SDK and Visual Studio 2015. Luckily I had a copy of the SDK in one of my backup drives from when I had originally installed it. The DotNetMicroframework I found online and the Visual Studio 2015 community edition I got from the Microsoft website. Frustratingly I was using a USB cable that had lost the signal so the power was getting through but no Netduino was being recognised. Luckily changing the cable fixed this. I then moved over my Rover module classes I had built for the original Rover project. Now I connected the Netduino to the Rasbperry PI via the serial GPIO pins on both devices. This then allowed communication between the two boards I then moved the logic from the MotionTrap project onto the PI.
