"I wanted to learn how a buzzer works and how to make it play different notes. I connected the buzzer with the Arduino and had it play a sound. Then I connected push buttons to the input pins and made if-statements in the code that corresponded with the buttons. Each button played a specific frequency that matched the notes of a piano. Lastly I added a button that would play a short song." /William, student at the technology programme
