Description:The thing I participated in for this project was the building where I built almost everything while my partner did the code we would start off by picking one of the builds to make as after that I would build the thing make sure its all good where I would go and look over it to make sure everything is fine until my partner starts creating the code where I wait for him to finish making it and then check if it works and we would repeat that process until everything was done.
Reflection:I believe I did my part in the project as I did the building and looking over the the things I want to keep working on is doing my part in the project

The LCD will display the words "Hello World" and show how many seconds have passed since
the RedBoard was last reset.
This sketch was written by SparkFun Electronics, with lots of help from the Arduino community.
This code is completely free for any use.
