For our team to successfully display what the VEX Robot brain displays onto a display screen, we had to use and code a Raspberry Pi to connect the display screen and the robot brain together through the Raspberry Pi as a medium. 

Here is the best model that our team has been able to create with the resources we have currently gathered. This is our finished prototype which we will be displaying at EXPO. 

This was an accuracy test to see if our Optical Sensor was able to pick up the three colors of the traffic light, or none of the three colors in general, which proved to be successful. 

This was a difficult test to run as the transmission was near instantaneous when the optical sensor captured and displayed the color detected from one to another, however, these were the rough results we got. All of them were below a second and, as said, near instantaneous, proving to be effective. 

This is where our Optical Sensor failed the most as it was not able to detect color from farther than 7 inches away without the color detected being wrong. This was the main struggle with our prototype, and we were not able to acquire a better sensor to better our demonstration of our product. 

Here, our group wanted to test the different brightness levels of our Optical Sensor in different lighting environments. The Optical Sensor can switch between 0% brightness all the way up to 100%, and we wanted to see if different environments would affect it. It appeared that only when we were in a dark space with no brightness levels did the Optical Sensor struggle to pick up red; however, after some retests, it appeared that this may have just been a flaw. The Optical Sensor appeared to work well within reasonable range to different lighting environments.
