takeaways

one big takeaway that I got from this project was how to make music on a piezzo buzzer. I know the basics of it  and that will really benifite me in the future.  I also learned about patience, there was many times in this project where I wanted to kill the computer but I was patient and asked for help and got through it. Lastly I learned  about making lights flash, make it brighter or not brighter and make it blink faster or slower.

reflection

my reflection  I had from this project was overall pritty good. I was really proud of how much stuff I did for the project, I was also suprised about how well I did in making the music. I was overal impressed about what our final project was, we created the mario theme song with some flashing lights. My partner did his job of the project and with some help he finished it on time.
