DC Control Panel

My Latest project is a DC control panel for my radio shack, it has 300W solar panel and 40A MPPT controller. It also has PC control via serial to an Arduino with a relay board, the control software is written in python.






Master DC Control Panel


WS2812B 24 LED RGB Ring apx 8cm for status signal 
Software running on desktop and android



The python code

  9. # This is a linux CLI program sends serial commands to the an arduino that switches a
  10. # radio shack control panel via a relay control board.
  11. #
  12. # It uses the letters A-F. Uppercase turns the relay on while lowercase turns it off the panel
  13. # has 6 swirches and relays hence A-F. A CLI program was choosen over a GUI as the code can be modified
  14. # with pygame to have a GUI or broken down in  to small parts and modules that would allow control with
  15. # things like cron or ifttt makers channel in the future.
  16. #
  17. # These are the devices that are being controlled
  18. #
  19. # A- Radio 1 FT8900
  20. # B- Radio 2 IC2200
  21. # C- Radio 3 FT 991
  22. # D- Diesel Heater
  23. # E- Accessories
  24. # F- Not Used (Spare)
