Yellow Tracked, Warning System Built, Prototype Made, Testing Success! - 25/06/15

Today's progress was immense.  First the BGR values for yellow had been added to the code.  These are as follows:

lower = np.array([10,100,100],dtype="uint8")
upper = np.array([50,250,250], dtype="uint8")

Then after the colour change, the warning system was then built.  The warning system consists of two parts, the warning light box and the buzzer.  Initially an HUD unit was to be used, however, a light box would be more visible throughout the day.  The HUD maybe a consideration for the future builds.  The warning system was first designed in both Multisim and Fritzing.  These schematics are found below.

Follow these schematics, the system was then put together.

After the warning system was put together, the unit was then connected to the Raspberry Pi via the designated pins.

It worked! Driving the vehicle through yellow lines triggered the warning system.  Below is the video of the testing of the unit.
