build battery level

[Juninho]

Can anyone help me on how to create a battery level with 3 color rgb led?
I want to leave on blue light, red light flashing low charge, green light full charge and when taking out the charger change to blue color

 

[Juninho]

and for the portable ps2, I'm still going to buy the bms and batteries

So you want a battery level indicator that works independently from an off-the-shelf charge/discharge circuit? Also what configuration of batteries do you intend to use? number of cells, and how many series, how many parallel?

in my project I just want the rgb led to change color, when it is low charge, red light flashing, fully charged green light, console in operation blue light

I'm thinking of 4 batteries, 2 parallel and 2 in series, I will also use a bms board

Well you have to use a BMS board, otherwise you run a very real risk of melting your device. But all that aside, what you're looking to construct is a circuit which includes a voltage senseing ic of some kind, which will be able to communicate with, or directly provide a programmable GPIO that enables you to turn on and turn off 3 different LEDs (seperate bulbs, or do you want to use a 3 color LED for a more space saving design?), and sense the presence of the charging cable when it is plugged into the device.

Have you done any browsing of Texas Instruments devices?

yes i will use a bms, the rgb led is only one it has 4 legs

this led changes color, there are 3 colors in it

 

[Juninho]

board i'll use this maybe

I always buy from Aliexpress, I think I figured out how to do it, I'm studying a chip

 

[Lightning]

Oh really? Which one?

 

[Juninho]

Oh really? Which one?

have the LM358N

 

[Customledmods]

have the LM358N

How would you make it work with this chip?

on YouTube there is a schematic, but there are other chips, I'm still watching
