Nice update - I was wondering about the reading you got. Your previous post noted a frequency of ~2735 Hz. This shows around 241 Hz. I wonder what value you have for

delay(CYCLETIME);

Since that could be limiting the output. I wonder what the trace would look like if you scope'd the A0 pin on Arduino to read what the ISD1820 is outputting.

Nice update on your design challenge project. The ArdunioFFT processing looks pretty powerful. Do the results match with your other experiments?

Keep up the good work.
