Introduction
Connect two Pushbuttons to a Bit Board and control a Piezo with code.
We'll explore how we can make sounds using a piezo speaker with two buttons.

We'll use Maker Tape to connect the two Buttons and the Piezo to the Bit Board on a LEGO baseplate.
-
Connect one Button to Pin 3 and the other Button to Pin 4. Both will also connect to Ground (GND).
-
The Piezo will connect to Pin 8 and to Ground (GND).
-
You'll notice the Ground on the Bit Board (as well as the Piezo, Buttons, and other Crazy Circuits components we'll use) is color coded White.

We're going to load the following code for our Piezo Melody program: https://makecode.microbit.org/_0uoJypV1r...
-
The micro:bit (since the release of version V2) has included a built-in piezo speaker on the back. You can use the built-in Piezo on a V2 micro:bit or connect a Crazy Circuits Piezo with Maker Tape as we've shown in this guide.
-
Each button will play a different melody at a different tempo.
-
-
-
Once the code is loaded it should start running immediately.
-
You can power the micro:bit via the USB cable you used to load the code or you can use a battery pack plugged into the Bit Board.
-
We've created two melodies by selecting a series of specific notes and you can hear each one depending which button you press.
