Post3: Repurposing bluetooth technique

In this week, we repurposed the code for lab3 part A. Previously in part A, we used bluetooth module to set and reset the LEDs on STM. For the purpose of our project, we want the bluetooth using UART to send signals to motor controller and the motor controller send voltage signals to DC motors. The first half of the code is finished. Also, we figured out and ordered the battery we are going to use to power up STM board without the USB cable. All parts have arrived except cr2032. We started on assembling the hardwares.
