Arduino auto-shutoff? Self-protection?
hi all,
i've got uno r3 hooked arduinix shield in order build nixie display. arduinix takes few arduino outputs , allows them control separate 180v supply.
when hook shield 1 of nixie tubes, runs great while, , ard quits sending output pins. (i've got led on pin in question, , voltmeter on test point in shield, know arduino has stopped sending pin high , not going wrong on shield.) if reset arduino, comes on again.
it doesn't when tube isn't connected (the led stays lit indefinitely). cause arduino stop sending outputs pins this? load problem? there protection fuse getting tripped? don't expect users here trace shield schematic , everything, should looking or metering in order figure out what's going on?
thanks!

how long "a great while"? watch doesn't have increment.
so know arduino has stopped sending pin high , not going wrong on shield.)
the arduino doesn't "send pins high". code toggling pin? (and have current limiting resistor in series led, right?) if code isn't directly changing state of pin, won't have debug information go on.
if reset arduino, comes on again
pressing reset button , getting normal operation, might suggest code problem. 1) running out of ram. 2) not declaring variables millis() , micros() correctly. 3) not handling rollover of millis() , micros(). etc.
is there protection fuse getting tripped?
there poly-fuse on usb supply line. however, simple press of reset-button wouldn't reset it. power cycle (and few seconds of power-down) needed let polymer cool down.
don't expect users here trace shield schematic , everything
probably idea set expectation there. tough trace schematic or debug code isn't posted. (hint: nobody ever complained posting code , schematic along question.)
