I have a very simple setup using an Arduino connected to a doorbell button.
I have a pull down resistor on the input pin, and trigger the code when the pin goes high.
The other side of the doorbell wire is connected to the 5v rail.
When the doorbell is activated it triggers some relays.
The issue is that it randomly goes off a few times a day for no apparent reason.
I have found that using the igniter on the gas stove can trigger it, and I think the washing machine can randomly also.
I tried it in reverse ( go low to trigger ), this was also randomly triggering.
Does anyone have any ideas of what is going on?
