Challenges

Can you complete the challenges? Change the code in your code editor above. Upload your code to see the effect when you're finished. Complete a challenge? Check it off the list!

Change the values inside the parentheses of the delays. Before you do, make a guess about what a smaller number (like 100) will do to the code!

Update the second argument in the setPixel function from 200 to something else. What happens? Can you make Bumblebee's eyes glow blue?
