I figured out that the total cost of the project was about 2.5$ because its a reuse project!(I reused a milk carton and turned it into this instructables robot night lamp, if you see carefully you will notice that the robot is the Go-Green Instructables Robot!
Here is a video of the finished project!
I even used multi color LEDs and it looked great!
This is a fantastic song(My 2nd favorite song)
