I'm currently trying to decipher how long my project could last in it's current configuration.
The program is using just 7% of the board's memory and I'm using an arduino Uno R3. The output is just a set of four LED's that serve as a night light using a photoresistor to determine the appropriate moment to switch on and off.
I have left all components working as they normally would, in other words I haven't taken any measures to minimize current consumption aside from programming efficiently.
I'm powering it using a set of six double A batteries and a DC connector.
Any suggestion on how to predict it's lifespan? Or is this an ignorant question?
Many thanks to any who help out.
