Hello everyone,

I have a music-system which can be powered by 230V AC or its internal battery-pack which has an output of 33,6V. There are 4 battery LED's (3x green 1x red).
The LED's are glowing voltage based.

Now I want to build a battery testing system which would measure and record (and display) the ranges for each LED (with an OLED display) but unfortunately I don't know where to start since I'm a trainee. I also want to measure the capacity of the battery (optional).

For example when its full charged all LED's are glowing, when the first green LED stops glowing, the system should record/save its exact voltage and optionally time. And do the same for all 4 LED's

Did someone do such a project before? Maybe with an arduino? I found a couple of arduino tutorials but not exactly what I was looking for and they work with very low voltages.

Or should I build the system with some operation amplifiers (and with arduino)?

I appreciate any kind of suggestion, directions, help and so on..

Thanks in advance,
Feyz7

What made you think that your question has anything to do with the Website and Forum section which is clearly stated to be for "Improvements for the web system, applications to moderator, spam, etc."? I have suggested to the Moderator to move it to the Project Guidance section.

Two or three hours spent thinking and reading documentation solves most programming problems.
