 We would like to thank our professor, Preet Kang, for giving us advice on what we can do to make our project better and keep us motivated throughout the process of doing it. The advice of boxing the hardware to make it look like a sellable product was helpful. We would also like to thank him for giving us the background knowledge needed to make the Real Time Operating System program running on our SJ One board.

 == Conclusion ==
+Once it was confirmed we had all of the parts we needed and the hardware was set up, the programming was all we had to worry about. We made introductory designs for each task and the phone application, but made lots of changes throughout the project. We eventually stuck with giving the user the choice to choose the direction and amount of liquid to be output from the syringe. This approach required more error checking and a fail safe design to make sure the user cannot go too far or too close with the syringe holder and break the pump. There were a lot of different methods tried for sending UART signals to the board, but we stuck with a loop that breaks down the input by 1s,10s,100s, and 1000s of steps on the phone application side. The Bluetooth task had to be altered multiple times to accept the large amount of UART signals in a short period of time.

	The task is designed to wait for a message from the Android application and handle the data transfer. It will discard all bytes sent until a start byte of 'x' is sent and it will enter a loop to receive all of the letters and translate it to the equivalent liquid output to calculate the total amount of liquid to be output from the syringe. It will discard all other bytes that are not part of the decoding key and will exit the loop once a done byte of 'y' is sent. The program will then multiply the amount of mL of the requested output with the number of steps per milliliter to determine the result and send it in a queue.

 The application accepts user input that is between 0 to 30 (max amount of liquid per our syringe) to represent a milliliter equivalent output. The input needs to be rounded to the nearest .5mL (how accurate our product will be). The application converts the mL output to an appropriate number of letters to be sent through the Bluetooth UART connection on the SJ One board to decode in a later step. The software protocol is to send the amount of liquid to the SJSU One board starting with an 'x' byte to signal the start of data transfer. Then the appropriate letters are sent ('a' = 1 step, 'b' = 10 steps, 'c' = 100 steps, 'd' = 1000 steps) afterwards until the exact amount is sent and then a byte 'y' is sent to signal the end of the data transfer. After the data is done being sent, the application will disable input until the stepper motor task sends a byte to signal that the process is complete to allow for another execution. The user has the ability to change the direction the stepper motor is turning so the syringe holder can be pulled back when done.
