Battery charge level and sound level indicator - KA2284

The module is based on the KA2284 system. It is used to measure the input signal with the 5 LEDs, which are gradually included depending on the value of the measured voltage. It can measure voltage AC or DC (selected using jumpers). Sensitivity is adjustable with a potentiometer. Works with voltages from 3.5 V to 12 V.
