I am using a Arduino nano clone and it is using the old bootloader. I am making a relay center to control various things on my new laser cutter. I have a 4 bank relay module and it works fine. I wired it up as it shows and I can open the serial monitor and run through the tests for the buttons and the relay and it all works. But when I hit reset and close the SM window it refuses to work. Now I am planing on using this in the protected mode . So I am going to run a separate power and ground to the relay to isolate the nano. But as of right now I have it wire as it has showed me. I am going to test it to see if there is any output to the relay when the button is pushed . Here is the code that was generated.
