In this experiment we learn to generate sound using a buzzer. The goal is to manipulate frequencies to produce a specific pitch. If the delay is increased the frequency is decreased accordingly. In order to understand the theory we decided to experiment using different delays which meant the periods varied. This produces different frequencies which might have a symphony if selected carefully. Musical notes can be easily composed by choosing specific delays. The buzzer can also be used to trigger an interrupt in alarm system.
