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 delay in the loop so the message 'prints' faster or slower.

Update the contents of the message.

Add some code:Serial.println("Loop Begins!");
at the top of the void loop function to show a different message when the loop begins.
