I am working with a ArduinoUNO - 2100 mA battery, and a solar Charger shield. I use a temperature reader that sends info every half hour with GPS-GSM shield called LONET (http://www.seeedstudio.com/wiki/LoNet_-_GSM/GPRS/GPS_Breakout for more info).
I want to save all the energy i can, i am trying to put Arduino UNO and LONET on Sleep mode.
LONE has its own mode via “AT+CSCLK=1”.
But for Arduino UNO i haven seen a library called Narcoleptic (https://code.google.com/p/narcoleptic/ for more info) wich can solve the problem.
My question is:
Is there any other method that can help me to save Battery with Arduino uno? is it a good approach to use Narcoleptic or there is another method to do it?
Thanks for your time/help and sorry for my English.
Any feedback could be welcome.
