I thought it was the Xbee until I wrote to the stream’s buffer instead of directly to the stream output." I too am communicating with one side of my Xbee's using C# code. What is the difference and how do you write to the buffer instead of the output? Thanks! Justin Hello,

Can you tell me more about what you mean by ” I was using C# and kept writing directly to the stream when I noticed a significant lag in sending and receiving data. I thought it was the Xbee until I wrote to the stream’s buffer instead of directly to the stream output.”

I too am communicating with one side of my Xbee’s using C# code. What is the difference and how do you write to the buffer instead of the output?

Thanks!

I have a fascination with LED lighting and I made a wireless "wall washer" using Xbee to individually control 8 high power LEDs. I'll be putting up documentation on the project sometime soon with the details on that. I am definitely continuing work with the Xbee modules, especially in home automation. I am working on possibly starting up a company to do Xbee related kits. Stay tuned. :) Andrew Thanks.

I have been 'playing' with these on and off over last year and a bit and they are really easy to get up and running. Your tips above are a good pointer to those just starting out. Cheers, Dale Nice wrap up.

I'm curious, what are you using the Xbee for?

Also,rather than just on and off - have you tried to connect multiple lights to include fade-in's/out's to denote beats other than a solid beat and silence?

I just sent a 1 or a 0 determining if the light should be on or not. If you wanted to actually play music via minim on the arduino would be a different story. If you wanted to interface with speakers, you could put the output from the analog output pins on the arduino through an amplifier (LM386?) and then to the speakers. I'm not sure what quality of sound you might get out of it either. If you dont have analog out, then a digital-to-analog convert -> LM386 should work as well. Thats more complicated though. Software wise, I would look at the AudioBuffer class in Minim to extract the sound data. Good luck, Andrew @Sally
