Servo-Controlled, Light-Tracking Solar Panel Platform Scott Mangiacotti Tucson, Arizona USA May 2018
Uses: Arduino Uno Two 180 degree servos Four photo resistors Misc electrical components Small solar panel Mechanical assembly
Description: This is another implementation of using two 180 degree servos and four photo-resistors to be able to track a small solar panel to align to the area of most light intensity.
The motors make small movements to try and point the solar panel to the brightest light.
There is also a multi-color LED to indicate if the system is enabled or not. And two push buttons to enable/disable the motors.
There are a few routines that can be used for moving the motors to commanded positions. The commands are via the serial port interface and a series of numeric codes/commands that can be sent to the Arduino Uno.
The independent move commands are programmed in a way to provide (somewhat) smooth motions instead of immediate position commands that cause the mechanical mechanism to move violently.
