I have received a number of emails requesting schematics for infa-red remotes. So here is one. This remote transmits a tone using an infa-red LED. This tone is decoded by the receiver. Since the receiver only switches when it "hears" the tone, there are no accidental activations. |

| i have chosen it as my minor electronics project i have realized it but did not able to make it work .can u suggest me some reason why? | ||
| what is rating of phototransistor where should R(1Mohm ) connected | ||
| sir you have not mention the rating of npn phototransistor, & any alternative for spst switch | ||
| the 1M resitance between IC1 and ground replace the capacitor?? or I just have to add it'?? I can't make it works. | ||
| how to find the maximum range of ir remote i.e. how to find the maximum diatance betwwen ir transmitter and receiver? | ||
| my mate is trying to take credit for this as his own, i was wondering if you had copyright or not,, so i can stop him muwahhahahahahhahaaaaa | ||
| Hello - does anyone have a circuit board layout for these two schematics? | ||
| Hey I have been searching all over the web for lists of simple schematics, and I stumbled upon your website. I am trying to automate my room, and I need to be able to control many (something like 5-10?) things from one remote. Is there any way to adapt this model so that I dont have to build 10 of each the transmitter and the receiver? Please email me if you have any suggestions or if you already have the schematics. Thanks in advance. | ||
| Question: Will an IR Receiver detect a deflection of an object passing through the transmitter and if so, what is the maximinum/minimum distance required between transmitter and receiver? Thank you, Joe Quarando | ||
