Frequency9. This is very short code that lets the robot make a sound from low to high. Note the greater than sign >, this tell the robot it is done.

Pitch and Frequency An important measurement of sound is the frequency. This is now we make low and high sounds. This is how fast the sound wave is oscillating or going up and down. This is different than how fast the wave travels through the air. Frequency is measured in hertz. The faster the sound wave oscillates the higher pitch it will have. For example, on a guitar a big heavy string will vibrate slowly and create a low sound or pitch. A thinner lighter string will vibrate faster and create a high sound or pitch. Learn more here.

Two sine waves are shown labeled Lower and High Pitch. The lower show 3 peaks and troughs the higher show 6.
