Simple Battery Level Indicator Circuit Diagram. This mode is selected by the external switch sw1 which is connected to 9 th pin of ic. Which be simple complicated can see that the circuit has will led keep for display arrive at 3 step.
It uses ten leds wired in a 10 dot mode. This mode is selected by the external switch sw1 which is connected to 9 th pin of ic. Battery charge indicator circuit design.
6 th and 7 th pins of ic are connected to the ground through a resistor.
The idea was requested by ms. I ve a project if you could help me out. So it divides the battery level into ten parts. The circuit works this way if the battery is at 75 all the green yellow and red will lit up which indicates the battery still holds 75 of charge.
