Arduino Audio Circuits

Let's say you have an LED display, and you want it to indicate volume from your TV, MP3 player, or other sound source. How do you make it work? With Discover Audio with Arduino, you'll learn exactly that. You will build simple to intermediate volume unit (VU) meters using LEDs, analogmeters & circuits, LCDs, and the Arduino. You'll also build simple amplifier circuits to enhance monitoring sound of radios, TVs, and MP3 players. You'll even learn how to use he online simulation tool CircuitLab to analyze simple amplifier circuits for VU projects and experiments. What you'll learn How to combine sound and LED displays How to do sound experiments with Arduino How to test amplifier circuits with CircuitLab How to build an Arduino-based volume unit meter Who this book is for Arduino and electronics hobbyists who want to learn more about working with audio displays and volume monitoring.
