Hello, I am building a circuit using a ATTiny, a 1.3 oled color screen, and two AAA batteries.
The batteries provide enough power to run the circuit, but they don’t run long before the 5v screen gets so dim it’s tough to see.
So I curious, do I restrict the power to the Mini and boost power to the screen. Currently I just have the power from the batteries running directly to vcc and using an output pin to turn the screen on and off.
I need to get 3 months of use out of the small batteries using deep sleep when the user is not using the devise. The users will probably use the devise 5 or 6 times a day fir a minute or two at a time.
I worry about adding any elements to the circuit that will cause more of a drain.
