FYI, it was a damaged board. On further testing A few pins were acting funny on that board, so I soldered pins onto a new one, and current draw in sleep is in the uA range.
No, no radio on board. I'll keep that in mind though for when I add the RFM73.
Hi all,

I'm trying to get an Anarduino Mini to sleep to prolong battery life. I'm using this code in a function called by loop(), which I put together based on an article at arduino.cc:



The chip seems to go to sleep until pin 2 goes LOW, as desired. However, my multimeter says the anarduino is drawing 50mA in sleep, and closer to 60 when awake and playing a short tune on an attached speaker. Both these numbers seem high.

I've tried a number of other sleep code examples online with no luck. Do I need to do something different with the anarduino to get low current draw during sleep?

Thanks,

Nick
