Hi guys,

I need your help with infrared transmission:

Which of the following can interfere with an infrared transmission?
Options ...
1) Too much light
2) EMI
3) RFI
4) Crosstalk

Thank you in advance,

That looks like a cut/paste from a school assignment.

The basic idea of a school assignment is to challenge you to figure out
a proper response based on your prior learning. This prepares you for
an actual job where you use your logical abilities and your prior
learning to solve problems.

Your welcome.

Which brings us to the essence of the problem. Less than 1% needs to
know how to use their brain to think reason with. The rest will work
at a place where they are told what to do. The schools got a totally
wrong focus on what is important for most ppl. Instead of producing
ppl who are enabled for work, they are producing ppl who got a mind of
their own, with the challenge this means for a leader.

i suggest you get a remote and actually try it.

>Options ...

try the remote in a dark room - how far does it work reliably?

then use a fllod light / room lights / sunlight and see if it
changes......
