Description

The core component of this 12V Battery Level Indicator Kit is the LM3914 IC, which converts an analog voltage input into a linear LED display. This IC eliminates the need for current-limiting resistors for LEDs, as it internally regulates the current, making the circuit more efficient and durable.

Designed to monitor battery voltage between 10V and 15V, this circuit ensures a clear and accurate visual representation of battery levels. The LM3914 IC operates within a voltage range of 3V to 25V, making it versatile for different power applications. Additionally, this IC is capable of driving LEDs, LCDs, and vacuum fluorescent displays while providing an adjustable reference and precise 10-step voltage division. It can also be used as a sequencer, making it a reliable and multifunctional tool for battery monitoring applications.
