Xbee guide
A comparison of various xbee radios. You can get up to 15 miles, probably more with line of sight, but the disadvantage is that you can’t rely on outside help, like ham radio operators to help decode the telemetry signal. From Sparkfun https://www.sparkfun.com/pages/xbee_guide
MIDI wireless options
A thought exercise – to come up with various ways of making wireless Midi systems based on projects I’ve already done. any combination of iOS and MacOS devices use touchOSC with above setup Arduino + ethernet shield to wifi router to touchOSC Same as above but using wifi bridge to connect to router* Arduino + …

Infrared Beam Sensors
Arduino Automated LED Stairway Lighting. http://www2.cs.uidaho.edu/~lawrench/electrical_projects/stairway_lighting/stairway40.html This project uses the Radio Shack emitter/detector LED pair 276-142 – There is no modulation of the ir signal. The project includes detailed descriptions plus photographs of the Arduino and breadboard configuration. Here is some more information about the RS ir emitter/detector pair http://www.societyofrobots.com/schematics_infraredemitdet.shtml
Detecting an IR Beam Break using the Arduino IR Library
A simple electric eye circuit By Ken Shirriff http://www.arcfn.com/2010/03/detecting-ir-beam-break-with-arduino-ir.html update 5/2014 – For current information, see the musical stairs project – using this IR library with sensors from Adafruilt: https://reactivemusic.net/?p=12300 original post I was able to build a version of this using some ir receivers from radio shack. The receivers were different – one received a …

Arduino field strength meter with colored lights
I’m not sure what this idea is, but it would translate radio wave field strength into light, musical notes, bar graphs, mechanical stuff, etc.,
Bicycle speed sensors
Arduino bike speedometer. by amandaghassaei at Instructables http://www.instructables.com/id/Arduino-Bike-Speedometer/ Radio shack magnetic reed switch. http://www.radioshack.com/product/index.jsp?productId=12706327 speed vest project… By Mykle Hansen at Make http://makeprojects.com/Project/Speed-Vest/1344/1#.UHcZaa5U3Tq Wheel sensor , from a wired (not wireless) bicycle speedometer (aka cyclocomputer) The sensor must perform like a reed switch, which is binary, rather than use the magnet on the spoke to vary the inductance. We …
