Hi,

I’m trying to get the value of my battery using an analog input of my ATTiny85 to create a gauge. To do this, I made a voltage divider to avoid draining too much battery. The problem is that I don’t understand why, after letting my project (which includes sensors and a screen) run for more than 24 hours, I’m still getting an input value of 512 with an `analogRead()`.

I haven’t applied any calculations yet, just retrieving the value from my voltage divider. But this value doesn’t budge at all… I’m using a 3.7V 400mAh LiPo battery.

Here’s my schematic.
