Product Description

KA2284 level indicates the module, battery indicator, audio level indicator

This simple circuit is based on the monolithic integrated KA2284, providing a simple and reliable VU meter with a LED that can visualize the intensity of a signal and therefore of its logarithmic scale voltage, thus allowing it to appreciate its size.
This circuit can be used as a VU instrument in amps and professional audio systems, but also by measuring continuous voltages can be used, for example, as a battery charge level indicator in any Arduino application, or other demo boards in how perfectly Compatible and simply implementable at the connection level.
