I need to build a circuit that will listen for a 3.5kHz tone and then activate a program on the Handyboard. I have seen a few different circuits in various books but none seem tailored to my specific needs. Does anyone out there have a good electret condenser microphone amplifying circuit for the Handyboard and can the handyboard decode the tone or should I build a 567 tone decoder circuit also. Any help would be greatly appreciated. John Edwards

(...) There's a circuit at the Seattle Robotics Society website, under the encoder. Sounds like it might be what you're looking for. -Jim Munro <jimmn@xnet.com> (24 years ago, 27-Jun-00, to lugnet.robotics.handyboard)
