As like most of the Made in China stuffs, Arduino remote control is dirt cheap. Although they cost cheap, it is sane to know details before buying. Here is Arduino IR Remote Control Module & Receiver Buying Guide. We performed some marketing research and found there are lot of guides for doing basic to advanced things. Investing $2-$3 behind this set is not at all bad idea.
Arduino IR Remote Control Module & Receiver Buying Guide
Actually there are different IR protocols, these China things usually use NEC protocol. The module part usually made by KEYES brand, the product information cum data sheet is this :
If you do not buy the receiver module, you need to buy VS1838B IR receiving head and create the receiver circuit yourself (which is not highly complex but impractical for small works). The module also has that VS1838B IR receiving head but ultimately the module has 3 pins – one is for 5V power, one is GND and the third one is for signal from Arduino. Setup is actually very easy. The module also separately sold which costs around $1. Cost of one VS1838B IR receiving head is just few cents.
It is important to give attention to the remote control unit :
There are 3 types of remote control sets in market – one is like the above, which is practical for most DIY projects. Others are probably parts for building Car MP3 players, so they have play-pause-equalizer buttons (which feels insane for many Arduino project).
Here is GitHub Libraries :
Total thing is sold as HX1838 VS1838 NEC infrared IR wireless remote control sensor module for Arduino at online shops. Here are some resources for in-depth idea and coding :
This much information should be enough for anyone to get ready to buy an unit and test with simple project.
