Picked up a freetronics MIC Microphone Sound Input Module at Jacar the other day. Let’s see what it can do. The ‘Hello World’ app from freetronics website reads SPL levels and writes them to serial port. Seems the values are 0-1023.

- www.tree-axis.com/Ess – turns up first in searches but looks ALPHA, buggy and messy
- code.compartmental.net/tools/minim/ – looks a bit neater and possibly simpler. Let’s start here.
