Enter, save, and run IrInterferenceSniffer.bs2.
Test to make sure the Boe-Bot sounds the alarm when it detects IR interference.
You
TestIrPairsAndIndicators.bs2. If you don’t have a second Boe-Bot, just use a
handheld remote for a TV, VCR, CD/DVD player, or projector. Simply point
the remote at the Boe-Bot and press a button. If the Boe-Bot responds by
sounding the alarm, you know your IR interference sniffer is working.
Disconnect your Boe-Bot from its serial cable, and point it at any fluorescent
light near where you plan to operate it. Especially if you get frequent alarms,
turn off that fluorescent light before trying to use IR object detection under it.
Always use this IrInterferenceSniffer.bs2 to make sure that any area where you are
using the Boe-Bot is free of infrared interference.
