(...) I have a few questions for you. How did you combine the 38khz and 500hz signal. In a design that I am working on now I have two signals similar to yours and an enable signal running into a three input AND gate. I haven't built it yet but it (...)

Well, at risk of being branded a heretic, since you've brought up the issue of modulated IR, I'm going to throw out an observation I've made about the Radio Shack IR sensors which several other people on the mailing list have privately disagreed (...)

At any point are you making an effort to detect your 40kHz IR signal? If you use the sharp IR detector to receive your 40kHz signal you are going to get an initial burst when the thing first turns on and then it will average out to zero just like (...)

Actually, I built the (...) This is exactly the same scheme I use. I'm using an IR module from Digi-key that has a side view, and five IR LED's spread around the front of the module at different angles. I have quite a few outputs, thanks to a little (...)

Matt, You mentioned an IR device from Digi-key. Can you expand (part no.) tel phone no. for Digi. Process analog info from IRs to digital data for HB? What IRs are compatible and where might I get this stuff. Your info into this would be greatly (...) (28 years ago, 5-Mar-97, to lugnet.robotics.handyboard)
