When you enter the Settings mode on your CircuitPet's menu, you'll be able to change the volume and brightness of the LED and run the hardware test that you should have done at the start of this guide.

If you later suspect that something is wrong with any of the components you soldered to the board, you can check if everything works properly by enabling the hardware test.
