Hello to all experts,
I have been given a project as described in the subject of this thread and I have found **broken link removed** this resource over the internet.
You can see there is a schematic in the given link which is also shown below
![FLYFQWXI52CWVYS.jpg FLYFQWXI52CWVYS.jpg](https://www.edaboard.com/data/attachments/57/57722-28a33ad85a4e39f9f280df87a474d084.jpg)
In this schematic, he has used two ICs of LM339 one is connected with solar cell and other is connected with battery.
My first question is:
Do I need to use both for this project? Or anyone?
And then he has connected 4 amplifiers to the pins (p1.0, p1.1, p1.2, p1.3) of the microcontroller. I have asked the author of this article via pm about these amplifiers. He replied these are LM339 quad comparator.
My second question is:
What are those LM339 IC's (blue) and what are these LM339 IC's (red) because if both are same then (means a single IC) both have same components connected to them.
Best regards,
Princess
