So i have a arduino pro mini 3.3v, oled display ssd1306, rtc and openlog.. i left this running with two AAA batteries for a day, every 3 seconds i was sampling data and recording it to the txt file on the openlog.
openlog was able to record 4800 data rows in about 4 hours powered with the AAA batteries, after that 4 hours(pretty good) my arduino pro mini and display keeps working, also the rtc but it is not longer recording. with time the battery voltaje drops to around 2.8-2.6. and openlog stops writing to the sd card.
do you have any idea why? if everything else is working?
No public wish lists :(
