Project from Real Time Systems subject which It consists of building an electronic system of a wagon connected to a computer from an external server. This system must perform some operations within the specified period of time.

We have two systems involved in the control of the wagon:

• Microcontroller (Arduino): This part will be in charge of obtaining information from the sensors and sending to the main controller

• Main Controller: This part collects the information from the microcontroller and execute the logical operations

1. Source_Code: It provides the codes for the micro and main controller parts. We have 4 different sections (from A to D), in which each one is in charge of controlling some of the sensors that I'm going to explain further.

2. Videos: This folder will contain some videos to show the implementation. Also, I have tested the behaviour of both parts when arduino receives messages from the main Controller.

1. Velocimeter: The Arduino will compute the speed at a certain period. This value will be send to the main controller. The speed is represented with a Led that has a variable brightness. The led will bright in a range between 40 and 70 km/h.

   

2. Light Sensor: The wagon has a sensor to measure the light outside. When the value of the sensor is too low, it means that the wagon reaches a tunnel. So, this value will send to the maincontroller for setting the lights on

   

3. Read the Slope: This sensor is going to detect a change on the slope of the wagon. This info will be received by the maincontroller to know if the wagon needs to brake or accelerate

   

4. Activation of Mixer: The brake system must be implemented using a LED that turns on when the brake is activated and turns off otherwise.

   

5. Brake and Acceleration System: The acceleration system must be implemented using a LED that turns on when the accelerator is activated and turns off otherwise. The brake system must be implemented using a LED that turns on when the brake is activated and turns off otherwise.

   

All tasks should check periodically the information about those sensors and sending to the Maincontroller.
