LED Signal Level Indicator Module for Arduino Projects

Add an LED signal level indicator to Arduino projects

Add an LED signal level indicator to Arduino projects. Utilising a KA2284 chipset, it is perfect for battery level indicator, battery charge indicator, Audio signal display, etc. 

The KA2284 battery level indicator contains five LED lights that progressively light up as the voltage increases. The AC and DC input of this module can be selected by a jumper and it can handle voltages that range from 3.5 V to 12 V.
