I have an external consumer product what I try to automate by connecting my Arduino to its push buttons. This device uses internally 5V, I can get this voltage on the switch buttons as well.
My goal would be to automate this without relays to keep my circuit small and quiet.
I have tried 2 methods so far:
-Connecting the buttons to the triac
-Connecting the buttons to the MOC directly
The results were the same. For the first time the switch works (device turns on) but any other attempts are ignored. I would like to understand why and how to modify my circuit to work possibly with the components I have on hand (TIC206 or MOC3041).
I got the triac in high power switching in mind because I didnt know what the device uses internally until I disassembled it but I would say the MOC should be good enough for switching 5V.
If I use a relay or just sort the wires by hand that works 100%.
