| Jun 14, 2019 at 13:31 | comment | added | Marcus Müller | @Andyaka I will design stuff for the heck of it :) No, really, this is an interesting project. | |
| Jun 14, 2019 at 12:38 | comment | added | Jasen Слава Україні | if you want simplicty use IRDA hardware - someone else has already solved that problem. | |

| Jun 14, 2019 at 12:09 | comment | added | Andy aka | Find a data sheet that specifies the reception capabilities of an IR transmitter and add it to your question. If you can't find one then you are dead in the water with this idea because no decent EE will design stuff without an adequate spec of the device's performance. | |
| Jun 14, 2019 at 12:07 | comment | added | MadHatter | I did this for a physics class in college, with colored LEDs to use as wavelength detectors. The need to be biased if I recall. Also the capacitance of an LED may make even 32k difficult. | |

| Jun 14, 2019 at 12:01 | comment | added | Jasen Слава Україні | all the applications i've seen had the diodes practically touching. is that 50c cost of a phototransistor so critical? | |
