ESP32 Built-in buttons

You have three built in buttons to work with: D0, D1, and D2

Here's a simple example that lights the built-in LED (on the underside of the controller) when you press the D0 button.

Here's another example that prints which button is pressed to the TFT screen.

Challenges

Can you have a different message show up for each button?
Can you control the colors of an LED module using the buttons?
Can you have each button display a different image?
Can you have one of the buttons display something random each time it's pressed?
