STM32: 4. UART & KeyPad communication (Bluetooth)

In this project, I'm using the HC-05 bluetooth module to communicate with STM32 by design a circuit and program the STM32L152RC MicroController to correctly parse the inputs from a keypad through USB FT232RL and HC-05 through serial (UART) between computer and STM32.

Extra features: There is also 2 extra features in this  project , first is when you press the numbers on KeyPad it will also shows the number pressed on the seven segment display; 2nd is in this program, it can also use the Android phone's bluetooth app (which I developed in AppInventor) to control the number displayed on seven segment display when the number is pressed on app.
