My apologies if I've double-posted the last entry.

With some more testing, I'm seeing that the arduino *isn't* locking up and the sketch continues to run, however the serial interface to my laptop is what is locking up. This happens on both the Uno and the Jeenode with an FTDI connector.

I'm going ...

Here are the things that I've tried, but none of them worked (as in, I'm still able to lock-up the arduino).

* Used an unplugged laptop (was using desktop previously)
* Used a jeenode with same sketch
* increased delay in the AnalogRead example sketch to 1s (up from 10ms).
* tried 5v and 3.3v VCC ...

Thanks for the suggestion Paul.

I do have access to an ...

I'm testing the current sensor before I put it into production and noticed something odd. I hooked it onto a portable electric heater and I'm using the AnalogSerialRead example code to see values coming from it. For the most part it works just fine.

Unfortunately, if I power off the heater rapidly ...
