Adafruit Wave Shield for Arduino Kit Suitable for measuring DC VoltageAdding quality audio to an electronic project is surprisingly difficult. People tend to end up either using low quality ISD chips (you might get 8Khz sampling rate for 30seconds out of these, if you're lucky!) or mucking around with trying to control a CD or MP3 player. Although it's possible to generate audio direct from a microcontroller using a PWM output, the quality is often low and it's hard to fit a lot of music in an EEPROM chip. You can buy
