Β Β Β The problem statement was, as a team of engineers, could we be tasked with automating a railroad system. However, there were multiple guidelines that needed to be followed. The train had to go through both the approach and departure gate. As the train went through the approach gate it needed to reduce speed. After a short delay the LED lights on the crossing gate need to flash in an alternating pattern, and shortly after the gate needed to go down. Once the train crosses through the departure sensor, the gate needed to go up, the flashing lights turned off, and the train resume its normal speed.
Β Β Β Starting from the station, as the train passed through the departure gate it increased speed to value 255, as programed. Once the train had reached the approach gate it reduced speed to value 170 and the LED lights started flashing. After the delay the gate would drop as the train passed it. Once the train was past the gate would rise up and the flashing LEDs would stop. The process then starts over as it goes through the departure gate again, as a loop. We, as a group were capable of following these guidelines to make it a functional and safe railroad.
