hi.
i'm new here.
i have some parts that i don't know what are they and what are they doing.
can anybody help me?

here is a picture of them:

#1 is just white, but I'm guessing capacitor
#2 is a transistor of some sort - the marking will tell you what - may even be a voltage regulator
#3 looks like an electric hot cross bun
#4 is capacitors
#5 is an LED (possibly IR)

IMHO
YMMV
there are only 10 types of people
them that understands binary
and them that doesn't

#3 is a 38KHz IR receiver.

#1 not sure - need a better photo.
#2 LM35 temperature sensor (can just resolve the lettering)
#4 Almost certainly electrolytic capacitors, but we can't see the relevant info on can - just the manufacturer's logo
#5 Probably IR LED (possibly a photo-diode or photo-transistor)

Judging by the marking #2 is a LM35 temperature sensor.

I agree with Docedison, I've got an IR receiver like that, which means #5 is probably an IR transmitter LED.

#1 looks a bit like a LDR (light dependent resistor). Is it flat inside with a squiggly line like this?

Please post technical questions on the forum, not by personal message. Thanks!

Hi,
Thank you guys!
Nick the sensor looks like this,i belleve it is LDR as you said.
Thanks again!
