Over Current Alarm with 15 Segment Bar-Graph Display

This Bar-Graph Display provides a high visibility  15-Segment Bar-Graph display  for current measurements. A buzzer provides audible sound when an over-current condition event occurs. The 15 segments are made with Red, Blue, Green, and yellow color LEDS. All LEDs are SMD size  1206. This tiny board can display  0 to 2A  current and provide an Alarm sound when the current level goes more than 2A. The project is Arduino-compatible and is based on an ATMEGA328 chip.  INA198  chip measures the load current across the shunt resistor and provides an output voltage to  ADC  of ATMEGA328. The microcontroller drives and controls the 15 LEDs connected to I/O lines.
