Subject: [alt-beam] Beam And IR light
I had an idea for a robot that could be activated by ir.
Think about it: a carbot that activies at night when you do any number
of things, like open the door. Even cooler is of you would use a photo
diode that actives when it detects someone's body heat.
Now for the real question-What is a relay, how does it work, and how
do you read the schematic symbol. I ask this because the only ir
transmitter receiver pair of schematics i have uses a relay. I suspect
it is like an electronic pushbutton switch, but that is a guess. any
help is welcomed
Thanks,
Brad
