Hey guys,so my problem is that since testing out a new 4-relay module for one of those
OEM Arduino clones - namely the Duemilanove 2009 AVR ATmega328p Module Board USB 2.0 Cable Arduino Compatible
. I can't get the device to either register on a couple of Windows 7 PC's (where it worked prior to this episode) nor work with an external power adapter(it just flashes out on plugin and the power LED on both the Arduino and a LCD+Keypad shield I've plugged in it are lighting up for a bit then start to dim and flicker).
So my questions are A) whether my Arduino dead or it's recoverable and B)If it is recoverable - how can I resurrect the little bugger?
-the aforementioned Arduino clone
-a DFRobot Arduino LCD KeyPad Shield (SKU: DFR0009) (plugged in ontop of the Arduino)
-a generic 4-relay module
(and not sure if it's relevant)- 4 Thermistor-based thermometers
I suspect that the flickering power LED might be caused by a blown voltage regulator,but I'm stumped why the thing isn't recognized via USB
Edit: I forgot to mention that the thing 'died' when the current program (a simple relay 1 through 4 'ON') ran for its first and only time so far and the screen dimmed quite a bit and after unplugging and replugging the USB cable the thing flat out refused to start
