Absolutely simple Arduino IR-repeater for Hi-Fi Gear Cambridge Audio CA-540A or other..
after i´ve made some IR-Remote substitutions for my Cambridge Audio CA540 Azur Amp (see „Project-1“ and „Project-2“ and so on) here on the site with first Bluetooth and then Web-Control i´ve finally made it „over-simple“ 😉 and use an Arduino (2,50$) + some IR-receiver (VS1838B)(0,40$) + IR-Transmitter (0,40€) + some dupont-cable (also 0,50$ incl.shipping)->on aliexpress by example..->Link,Link,Link
the point was the right library for this and i used (many,many thx to „Eddy Yanto“ !!) the simple IR-repeater-library on github->https://github.com/eddyyanto/ir-repeater
point was that in description it says:“..This sketch receives the infrared signal on standard pin number 3, decodes and dump the infrared information on Serial and forward the raw infrared signal to pin number 4.“; but that works not !!
in the .ino on the other hand it says:“..int RECV_PIN = 4;
IRsend irsend; // Defaults to pin 3“ and thats the opposite !! (works with the .ino-settings now of course)..
tried to reach him via e-mail to correct the description->no success until now..
anyway, u can now use almost any (hi-fi)-remote; place the ir-receiver at some point near u (and to which your remote can point/send to of course), make a dupont-cable-connection to your arduino in any length u wish and from there also in any length to the ir-transmitter !!
(the sketch only receives + transmit->no more other modifications to do in the sketch !! (noob-friendly 😉 )
easy as this and thats it ! 😉 (Total costs: 4$)
(working sketch is here btw.->Link) and on Github of course, again->https://github.com/eddyyanto/ir-repeater
by that i´ve bought some Burson V5i as D (Dual) and will report then about it !!
greets for now 😉
