 === Display Power supply issues ===
 During the earlier phases of the project we were using a generic 5V-4A DC power adapter to directly connect to the power input of the LED matrix. This led to the display being extremely unstable and almost impossible to use for testing and debugging. This also wasted a significant amount of our time. We realized the issue was the power and quickly switched to a buck converter that outputs stable 5V voltage. Furthermore, we also switched from using just jumper wires for data pin connections on the LED Matrix to using a combination of jumper wires and a ribbon cable. This fixed the issue immediately and it worked flawlessly henceforth.
 === Timer countdown issue ===
@@ Line 487: / Line 485: @@
 When we first implemented the timer, we noticed we needed a way to have the timer begin and display on the screen only during the gameplay and not during the Start screen or game over screen. Since the timer was its own task and not part of the state-machine, we could not control the timer behavior like we did all other elements. Therefore we decided to make use of some FreeRTOS APIs like vTaskSuspend() and vTaskResume() to our advantage. We suspended the task task as soon as it was created and only resumed it when it was required and suspended it again. This ensured the timer bar showed only when necessary and the gamer did not go into game over state every time due to the timer going to 0.
 === MP3 music play issues ===

 == Conclusion ==
-Conclude your project here.  You can recap your testing and problems.  You should address the "so what" part here to indicate what you ultimately learnt from this project.  How has this project increased your knowledge?
+Working on and developing Lumberjack was extremely fun, thought provoking and we never got bored. All the technical challenges allowed us to develop a more practical form of problem solving skills. Working with hardware can be a whole different kind of problem solving skill as we experienced. Overall, we applied almost all concepts we learnt in the CMPE 244 class and learnt even more while working on the project. This opportunity also helped us develop teamwork skills and better time management. We used FreeRTOS practically and by doing so we dived deep into the concepts and developed a concrete foundation of the knowledge. This project also increased our confidence for working on embedded projects or facing interviews.
