Pages: . Simple IR barrier sensor for arduino. I would like to build a simple IR barrier sensor and wondered how to wire it. Any simple ciruits out there? Visit my blog! Re: Simple IR barrier sensor for arduino. Thank you for your reply! I would like to avoid environmental interferences so how to modulate a IR signal? What I want to do is: 1. Understand how to build a sensor like this in general for future projects.
Maybe I want to build a machine to sort coins so I would like to detect the size of a coin and if a coin has reached a physical place in the machine. Thank you very much!! Links work for me, opens into pdf docs. Sorry if the links didnt work for you. Is it possible to build a barrier sensor just with these components without external ICs etc.
Of course resistors? Is it possible to modulate a beam just with eg. PWM of the arduino? Could someone provide a very small code example just as a hint? It would be nice to read the state of the IR barrier sensor as simple as this little sample: Code: [Select].
Thanks for your input and help. I will have closer look on the modules which allready send at a certain modulation. Thanks for your advice!
