Nate1206:
So there are a lot of home appliances that I would like to detect status of. Examples would be is the coffee make brewing, what cycle is the washing machine on, things like that. All of these statuses are usually indicated by an LED light on the appliance. I's it out of the realm of possibilities to plug into these LED lights to see if they are on or off? Not by light sensing but through splitting the wire to the led and detecting the voltage?Thanks for the input!
I have no idea what you mean by "splitting the wires". Do you mean cut the legs on the LED if they have legs or unsoldering them from the circuit board if they are SMD LEDs?
There is nothing stopping you from trying your plan and seeing if it works. Probably nice to have a DVM to check what you are working with.
