Hi guys, I hope you and that you enjoy this project. There are some ways to increase and decrease the volume. If you are on a computer, then press the up arrow key to increase the volume and the down arrow key to decrease the volume. If you are an iPad or a tablet, then press the star in the corner ( there are two stars, you may need to click both , one of them doesn’t work ) to increase the volume and decrease the volume press the back drop.
