The Arduino Sun Harvester Shield V2.0 is used to turn the popular Arduino Microcontroller into a platform
for controlling various types of solar machines such as sun trackers and heliostats. This shield is even capable
of controlling multiple machines when used in conjunction with the Sun Harvester Shield Breakout Board and multiple Sun Harvester Driver Boards.
Version 2.0 of the Shield is largely the same as version 1.0. The biggest improvement is the addition of a quick connector in the upper right hand corner
which allows you to connect the breakout board or driver board (using an adapter) to the shield without having to do any soldering. Additionally, the Wind Protection Mode switch
Target Changer Potentiometer, and SDA, SCL connections have been changed to screw terminals to further minimize soldering.
Shield comes fully assembled and tested with Lithium Battery for RTC. Some soldering skills are recommended
for connecting external circuitry to the shield.
Built in Features:
*Real Time Clock with battery backup.
*I/O Expander to extend the number of outputs for controlling multiple machines.
*Switch to activate manual control through the Serial Monitor.
*Switch to turn a heliostat into a sun tracker (useful for when first aligning the machine).
*Joystick for manual control of machines, especially useful when programming heliostat targets.
*Buttons for activating joystick controller and scrolling through multiple machines.
*Option to add XBee wireless using the XBee Adapter kit from Adafruit.com. (This is still in the early development stages)
*Labeled outputs for connecting stepper motor driver boards, limit / homing switches, wind protection mode switch, and target changer potentiometer.
