I'm not sure if this is necessary but this doc tells me that I have to put some R's and C's in the circuit:

TSOP382 IR Receiver Modules for Remote Control Systems (Datasheet PDF)

enter image description here

How do I know what value I need? And what is that µC thingy that is not explained?

Thanks for helping Mike

  • µC = Microprocessor.

µC is an abbreviation for microcontroller and just means the device you are using to read the signal (in this case the Raspberry Pi).

The capacitors and resistors aren't really needed for a hobby application. I never bother.

Power from a 3V3 pin and you should be good to go.

  • Thanks for the reply. I wasn't aware of this abbreviation so thanks for explaining this. In my current setup everything's working fine without R's and C's so I think you are right. I'm interested in the correct way of using things so I wanted to ask here...

  • @Mike1993 For the correct way you are more likely to get a proper answer at electronics stack exchange. The legend does suggest the R & C are only needed if the power voltage is less than 2.8V.
