hey everyone,
I am building a simple IR transmitter and receiver to be able to detect things. The idea is that : I put a receiver on an object I lose often (say keys,remotes etc.) and when I want to find I use the transmitter to locate it. I could put some beep sounds when the receiver detects the IR signal.
Now a goole search is just too vague and broad. What I have gathered is that I could use a simple phototransistor but they might not be that useful in sunlight. If I go about a proper IR receiver module (e.g. TSOP11..) then they demand a suitable data format.
So,
Question 1 ) shud I use the phototransistor ? I can make the scope (or range) narrower by putting tube around it.
Question 2 ) If I use tsop1138 how can i make the transmitter emit pulses (in other words how do I make use of ..555timer to make pulses ) ?
Any help, ideas, suggestions are more than welcome.
Thanks for your time
