solarLCD Example - eS2 Pro

This example sketch is designed to demonstrate the low power abilities of the energyShield 2 Pro and the ability to implement a maximum power-point tracking (MPPT) algorithm for solar charging. This project runs an LCD display from the RAW battery voltage pin that does not sleep. This power is used to maintain the LCD display even while the power to the Arduino is turned off. When solar power is available, the Arduino runs a MPPT algorithm to maximize the power generated by the solar panel.
