i have a PIR sensor, an audio shield v1.0, an arduino mini pro, a step up circuit and a 2700 mAh LiPoly battery.
simple project: play 3 min recording when motion is detected during business hours for a week with no or as little recharging, (contact) as possible.
i could add to my sketch the battery life optimization of toddh's "Easy-to-use, flexible data-logger sketch optimised for battery life".
or use the PIR to turn on the arduino and play the recording once for each instance of motion.
any thought about which combo would last longer?
thanks
