I search many thread about how to monitor 3.7v lipo while powering the board i use (nano).
But i think non of it successfull, i even try using Battery.h library but dont know if i do it wrong or just it wont work (try the examples)
Can anyone guide me how to make a battery (voltage?) reading while powering the board?
I want to display the discharge of the battery powering arduino nano on ssd1306 oled.
I found this library, which is like what i want to do now, schematic from the site
My project use arduino nano with ssd1306 oled and some sensors.
Really how to use this library actually?
Feeling so dumb
