• Develop laptop (4) software to:
    • Control the hardware (1) through DCC++ commands sent to:
      • Raspberry Pi (3) 
      • Arduino (2) 
    • Control the hardware (1) based on: 
      • Assigned problem and 
      • Hardware status reported by Arduino (2).
      • Turnout status reported by Raspberry Pi (3)
  • Plan:
    • √ Get simple communications between the laptop (not JMRI) and Raspberry Pi.
    • √ Test all the added commands to the Raspberry Pi.
    • √ Add throttle to control a train.
    • Use sensor status to set signals.
    • Use components to run "Grand Tour" script to run train, wait for sensors, set switches and semaphores.
    • Build a simple no options figure-8 to show signals 'wake' and 'bow wave.'
    • Build GUI to select problem parameters.
