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.

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