Ozan Sanci / Mbed 2 deprecated TPJ_prjct_Ozan

This is my TPJ project that controls the SLA battery charging cycle with 2W 12V Solar Panel and provides real-time data for user via LCD screen and Bluetooth

Dependencies:   N5110 Terminal mbed

Automated Solar Power Harvesting System

• Controls the charging and discharging operation of power bank with solar panel as well as house hold load and informs the user via Bluetooth and Internet of Things (IoT)

• Operated by FRDM-K64F: Kinetis Development Board that has ARM Cortes-M4 processor

• Programed with Mbed online C/C++ IDE.
