OR instead of dropping 200$ on a scope and arduino you can prolly get a "programmable IR remote" for similar price, but cant gaurentee its compatability, or that it can do a macro(multiple instructions with one press of button). Once you get that info you are ready to transmit, add a button, use a transistor and IR LED, from there its just programming, which you will need to taylor to yourself with the info received from above, another step where an actual scope would be invalueable, I can't help with IR circuit, since i didn't use a transitor and got results but not a good but im sure someone can post one if needed. Not something id really want to do as a first time project, but an arduino can run that.įirst you must note that devices may use seperate frequency, although most run on 38khz, you will need to verify that with a sensor and a scope, (not sure but a IR photo cell attached to a cell phone mic jack and read with a spectrum analyser MAY get you results required).Īlso inside that frequency is a binary code, which you will need to scan on each device to get the on off instruction. so pretend you are explaining it to your 11 year old.
remember you are talking to an old mechanical guy.
#SIGNAL GENERATOR GENERATOR#
is that something i can buy off the shelf ? a programmable ir signal generator ? or failing that, how much would something like that cost to build? OR could i hardwire the remote's circuit board membrane switch to a relay or something ? so the question for you guys that actually know about this stuff. i know i can simply take the existing remote and make a device that pushes the button and on the face of it that seems simple enough but for a variety of reasons i need something more reliable and elegant that that. i believe i can program all the devices on the same frequency so i only need a single/dual freq device. i need a device that acts like a typical ir remote control to control a bunch of devices simultaneously.
I am a long retired ME and well out of my area of expertise and need some help, please.
