NUC Fan + goes through resistor to A0 Nuc Fan Ground goes to gnd
Current sensor: (holding right angle connector on top of board, with pins facing your chest): left: gnd (gray) center: out (purple) right: vcc (blue)
Green (ground) and Yellow: Momentary Switch Yellow (Ground) and Orange: "Stay On" Switch Black (Ground) and White: USB cable, plug into yellow port on NUC Blue (ground) and Green: PSU 24 pin connector Brown (ground) and Red: Power switch of NUC
Connected to NC so that if arduino is unplugged, default is fans ON Yellow jumper goes in position farthest from relay module
Do not reboot the machine shutdown -r now If you want to reboot, just do shutdown -p now. The power management Arduino will reboot the machine iff the "stay on" switch is "on". To physcially reboot in a nice way: move "stay on" into the "off" position, and then press the momentary power once.
To shutdown the machine, turn "stay on" switch to "off" and then shutdown -p now. OR, press the momentary power switch once (and wait for slow poweroff). OR hold the momentary power switch.
If the machine is off, to turn on press the momentary power switch, or flip "stay on" into the "on" position.
If all else is powered, but arduino is off, the PSU will default to on. This could be avoided with a relay or a resistor?
when rebooting, the USB goes low and that is our first sign. The Arduino must now glitch the drive off and on with a delay. This must be timed right so that the BIOS? catches the PCI cards and makes them avail to truenas. In the case of a poweroff signal, this USB goes low and the ardiuno can't tell the difference. So what we do is the same glitch, and then wait for the USB (aka the cpu) to come back. if the USB stays low then the drives shut off for good, until the next button press.
Note these were taken with printing on, so I will leave it on
Inorder to find this time, I added a debug button and so far: 50 bad
150 good, after the 50 was bad
150 and 250 are every other reboot
at 350/450/650 they became de-synched from eachother
same with 1050
I will try 150 again, incase it must be after a bad reboot to be good. In this case I could just ssh in and reboot twice which would be annoying, but not end of the world.
Arduino projects cannot have a hyphen.
