jiayi li / Mbed 2 deprecated DIY Mbed Dual Axis Soler Tracker

This program uses the "PSA" solar positioning algorithm calculating the sun position, based on longitude, latitude, and time zone. Then Mbed chip controls the two digital servos to rotate the solar panel to the correct azimuth and zenith angle.

Dependencies:   4DGL-uLCD-SE AX12 NetServices mbed spxml
