Challenges

Can you complete the challenge? 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!

Switch up the digitalWrite or tone statements so that the motor only buzzes when the tone is off.

Add some analogWrite functions along with more tone functions - can you get the tone to rise as the motor vibrates harder?
