More of my EV kick coming through. A solar tracker is used rotate a solar panel to get optimum energy from the sun. This one uses LEDs as the light sensor and mosfets to drive the output to rotate ...

The other panel is wired up the opposite way, so if it is in the sun, it brings the other panel into alignment as well. This serves as a very simple planar solar tracker. If you want to track the ...

The proposed tracker uses two different sensor types ... of UV radiation received from the sun, and the MEMS sensor forecasts the sun's path across the sky,” they added.

The scientists describe the tracker as a low-cost device using ... the panel in accordance with the positioning of the sun based on the sensor data transmitted and processed by the Arduino Uno ...
