This project is based on a netduino mini, it uses a pair of linear actuators to move a set of solar panels so that they face the sun throughout the day.
Knowing the latitude, longitude and the date/time, the software calculates the azimuth and elevation of the sun. The system is setup and calibrated using an android or windows app that communicates with the device using the bluetooth interface.
The circuit includes;
- Netduino Mini.
- DS1307 Real Time clock with battery
- Bluetooth interface.
- I2C interface for the LCD display
- Four BTN7960 Motor Controllers
