Use Any Old Infrared Remote

  1. First collect a whole lot of old remotes from friends/relatives/enemies!
  1. Attach the $5 Arduino clone and infrared sensor
  1. Run the IR analyze program that is provided when you download the
    "Free" Arduino programming software.
  1. Now work out what "numbers" if the infrared remote is actually sending.  Of course, not all infrared remotes can be decoded, but you can try!
  2. Once the infrared remote has been decoded, you can use it in a code line like this "If SensorValue = 1410 ThrowToiletRolls(10)"
