Large Size Bar-Graph Voltage Monitor Using Arduino Mega and 20 Segment 3W White LED

Simple 20 LED  Bar-Graph Voltmeter , each LED display 0.25V, this circuit can measure 5V directly or its can measure higher voltage range using resistor divider.  Example circuit for resistor divider. If choose Z1=10K and Z2-10K it can measure 0-10V. Turns on a series of LEDs based on the value of an analog voltage input.  This is a simple way
