The final board is ready for take off…Thanx Martin Nawrath from Lab3 KHM, Cologne.
Besides going wireless, we are now able to control the sensitivity of the piezo elements.



After having problems with the Arduino Board, we decided to use the XBee Module and
it`s internal D/A-Chip. We had to go wireless for the inlay anyway , and the first test
board seems to work perfectly.
