| Hi there all,
i just want to ask you a little question.
I'm a newbe and i finish to read some articles on gammon
about power saving of arduino.
I have a pulse counter tha i want to make it to save more power possible.
The problem is that i need a timer in order to know
the time between the last 2 pulses every about 5 minutes.
If i understant, if i power down the arduino, i lost the mills().
But if i use an external timer2 using a 32 KHz crystal
i can wakeup and have also the time.
First of all ... is this correct that i understand please ?
Thanks a lot

| Can you please post Arduino questions to their forum?
http://arduino.cc/forum/
You can send me a PM (on the Arduino forum) giving me a link to that thread if you like. |
