Arduino Piano

Supplies

Arduino board

Membrane keypad

Buzzer or piezo buzzer

Jumper wires

Battery or USB cable

Wire cutters

Soldering iron and solder (optional)

Step 2: Connect the Membrane Keypad to the Arduino Board

Step 1: Connect the Membrane Keypad to the Arduino Board

Connect the six pins on the membrane keypad to six digital input pins on the Arduino board, according to the wiring diagram for the keypad and the Arduino board. If necessary, use a soldering iron and solder to make the connections.

Step 2: Connect the Buzzer or Piezo Buzzer to the Arduino Board

Connect the positive lead of the buzzer or piezo buzzer (usually red) to a digital output pin on the Arduino board, and connect the negative lead (usually black) to a ground pin on the Arduino board.

Step 3: Write the Code

Use the Arduino IDE (Integrated Development Environment) to write the code that allows the Arduino board to detect keypad events and play the corresponding music. The code should include the following
