![]() the output intensity at a port can be varied by varying the optical. If you need to, you could get on the LEDs to figure out which connection is active.Īlternately, many of the electronic optical switches have an IR remote, and if you could do everything with the remote, there is a great volume of material on using Arduinos to replace IR remote controls. 5.7 where only port 1 receives an input of an intensity Iin while port 2 receives no. One side of the button will probably be tied to ground, and the other pulled up to VCC (hopefully 5v, which is likely since it's got a 5v supply), so pressing the switch will ground both sides (check with multimeter to make sure this is what it's doing).Īssuming all those assumptions I made are true, tie switch ground to arduino ground, and run the other side of the switch to any output pin, and pulse it low to simulate pressing the button. (example, not product endorsement: ), and hijack the button to control it. simultaneously bunch together to come out from either one of the output modes. You need an electronic optical audio switch - one that requires a power supply. For a symmetric beam splitter, r1 Dr 2, t1 Dt 2, we can rewrite Fig. I would recommend taking a commercially available optical audio switch and using that. Switching optical audio is hard (if you look on amazon, the cheaper optical audio switches are purely physical - they're switching the audio with this dial that physically points the fiber that the input goes into at the selected output). Hence, check out whether or not the switch box has the functionality to do so.I assume you want to control it with the Arduino?
