Hi, I made this post because I need help because I have an end of year project to do and it's a group work. We must display the battery of a coupler of 4 batteries set in 4.8V, so we must see a battery logo at the top right of the screen and the battery in % marked in the middle of the screen with a bar and have a small logo to know if we recharge the battery, The problem is that I'm a beginner and I don't know anything about C++, I've tried to make programs to display the battery interface but there's nothing I can do, I would like to know if someone can help me to create a program to make a battery interface, because for the moment I want to focus on the "interface". I provide you all the documentation of my LCD screen, at the bottom of the site you will see a datasheet with an arduino library and a datasheet with examples of codes as for example a paint on arduino.
Hmmmm .. this is homework type question.
I don’t like these because if someone here does it , you learn nothing .
Your task master cannot have asked you to do this , in that specific way without any coding lessons .
So have a go , people will help with odd coding issues , but you have to do the learning , or it’s pointless .
Post up what you’ve done and some circuit diagrams .
Hopefully you know each battery chemistry is different. The easiest would be to use lead acid as the voltage curve will give you the approximate charge. That can be read with one of the A/Ds after proper conditioning. For Li etc you need to construct a coulomb counter.
