I created a sound to represent the static on the TV. I then used mouseX and mouseY to control the frequency and volume of the sound respectively. To change the TV screen or the “channel”, I uploaded different images and sounds so that when the mouse leaves the TV to the left and right, the channels would change accordingly.
