I want detail information of battery level indicator project using pic controller(report).

battery level indicator using pic

Aim of the project:

To prepare a system that can operate devices even in the absence of electricity. When the electricity is not available the discharging of a battery after digital to analog conversion is used to operate the devices. In combination to this battery level has been displayed on the LCD.

Making:

The inverter circuit uses only four resistors and two transistors, and one transformer. Transistors could be NPN or PNP depending upon the polarity of battery. The DC input is given to a DC to AC converter. This is known as inversion. The output of this circuit is AC.A combination of Transformer and Transistors is used for the DC to AC conversion process. The output of this module is AC.
