 ## Testing It Out
 Once you have uploaded the code to the board, it should start generating a sine wave oscillation on the DAC, that depending on the frequency could be used to produce sound on a piezo buzzer or speaker. If you have an oscilloscope at hand, connecting its probe to the DAC output might be an interesting exercise so see what the wave looks like.

 The sketch above generates what is known as a sine wave. It is called a sine wave because if you were to plot the voltage against time, you'd notice that the line looks just like a sine function.

 There are other types of analog waves that will produce a distinctly different type of sound compared to a sine wave. The library we're using in this sketch also allows you to create sawtooth and square waves. These types of wave also gets their names from how they look when the voltages are plotted against time.

 Try changing the wave type and listen how it changes the feel of the sound. 
 
 Change the wave by replacing **Line 18 in the sketch** "`wave.sine(freq);`" with either
