Velleman KA02: Audio Shield for Arduino® Kit

Velleman KA02

Velleman KA02 Audio Shield for Arduino® Kit (Electronic Project Kit - Soldering Required)

If you need to add an audio message to your Arduino® Uno™ project then the Velleman KA02 Audio Shield is the kit to build. Record your message with the on board microphone or use the line input. You get 60 seconds of recording time and can playback your recording through a speaker or through the line output. Use the on board pushbuttons for REC, PLAY, FWD, ERASE, VOL, RESET and FEEDTROUGH or program the actions in your sketch. The Velleman KA02 circuit is based on the ISD1760PY integrated circuit. There is a downloadable example sketch and library to get you started writing your own sketches. The KA02's ICSP pins on the UNO™ are used as a serial connection to the shield to free up I/O pins.

Also available in a mounted module version VMA02.
