Project 212 Sensor Demo Robot

This repo provides robot code to run a demonstration of several types of sensors. Currently, the sensors include:

• Simple digital sensors
  • a limit switch
  • a Hall Effect sensor
  • an infrared proximity sensor
  • a beam break sensor
• Analog sensors
  • an ultrasonic rangefinder

Code structure

Unlike a real robot where a sensor would be a small part of a subsystem, in this code each subsystem contains one sensor and nothing else. The commands2 library (which defines the Subsystem base class) allows subsystems to implement a periodic() method, which will get run automatically with each update -- it doesn't need to be called from the robot's periodic() method. We use this feature to implement periodic() methods that update the Smart Dashboard with each sensor subsystem's sensor value, as long as the robot is enabled.

Since there are no user controls (such as a joystick) which could trigger robot actions, and since each sensor subsystem reads its sensor and updates the dashboard... that's all the robot has to do!
