The project is based in a kickstarter project that I have live now at: [login to view URL] The shield and code are tested and working for Uno and Duemilanove. However, on the new Leonardo, I get errors.... arduino_audio_sine_1:82: error: 'TCCR2A' was not declared in this scope arduino_audio_sine_1:82: error: 'COM2A0' was not declared in this scope arduino_audio_sine_1:83: error: 'COM2A1' was not declared in this scope arduino_audio_sine_1:84: error: 'WGM20' was not declared in this scope arduino_audio_sine_1:85: error: 'WGM21' was not declared in this scope The code is attached. I will supply the shield, you supply the uno and leonardo
