-Show a simple table or figures that show your scheduled as planned before you started working on the project.  Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals.  The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

 This line of code calls the addHandler function of the terminal file and adds it onto the menu. The user  can type up the command “Alarm on”, “Alarm off”, and “Alarm Status" from the command terminal to get the results. The user commands from the Android App will be directed to the terminal Arm and Disarm the security system.
+The MP3 decoder board is interfaced to the base station's micro-controller via GPIO pins. An 1K of inline resistor is used between the two boards to limit the current. The two GPIO pins from the base station translate into four states in the MP3 decoder board. There are three important tasks in the MP3 board, and they are buttonTask(), userInterfaceTask(), and mp3Task(). The button task initializes the GPIO pins , sets their direction to input. The task keeps listening for a signal from the base station and  send it to userInterfaceTask. The userInterfaceTask initializes the SPI, I2C MP3 decoder. It decodes the singnal and determine which MP3 to play. The userInterfaceTask then queue the MP3 name to the  MP3Task. The MP3 task receives the name from the queue and opens the file from the SD card. The task reads 1024 bytes at a time to MP3 decoder to play.
