 The coffee making machine uses [http://www.socialledge.com/sjsu/index.php?title=Embedded_System_Tutorial_UART UART]to establish communication between two microcontrollers using their Tx and Rx pins, more specifically UART2. The first SJSUOne board is used to control the motor to stir the coffee, step motor for coffee powder flow, and the cooling system. The second microcontroller is used to control the switches for user interaction and also to transmit temperature data to the first board. Since the boards can only supply 3.3V, a transistor connected to 5V was used so that the different I/O components can receive their appropriate voltage. The stepper motors have more wires than the regular DC motors, so more than one pin was needed to use them. The only non-electronic component of our design is the water valve, this is because of security measures.

 == Conclusion ==
-The coffee making machine was a learning experience and we learned to interface different components to the SJSUOne board.
+The UART Coffee making machine was a learning experience for both of us. We learned to interface different components to the microcontroller even if the microcontroller's 3.3V was insufficient. The hardest part of this project was getting the UART communication between the two boards, however, working together made it easier because one partner was able to check the other person's work. A non-techincal hurdle we faced was timing because we both had different schedules due to finals, so working together was only possible after finals. Overall, we are pleased with our project's results and the knowledge we picked up and reinforced along the way.
