Overview
--------------------
* Name : MAX471_VI_Meter
* Title : Arduino Project , Voltage and current meter based on MAX471 sensor
* Description :
1. An Arduino Nano uses a MAX471 current and voltage sensor to measure a Load
and displays output to an ERM19264 UC1609 LCD
2. Current reading range 0-3 A
3. Voltage reading range 3-25 V
4. ATmega328 battery internal reference voltage used for analog measurements
5. Output to LCD and serial monitor
* Author: Gavin Lyons
* Arduino IDE: 1.8.16

Libraries
------------------------
Libraries used , both written by Author and on github.
1. [MAX471](https://github.com/gavinlyonsrepo/MAX471)
2. [ERM19264_UC1609]( https://github.com/gavinlyonsrepo/ERM19264_UC1609)
Notes:
When using the LCD library fonts 1-3 must be enabled in font file and multi-buffer mode
selected. re MAX471 library, If deciding to use a different IC not based on ATmega328p the Vref would have to changed from VCC_BAT in constructor.
