Hello All,
I am new to electronics and I am trying to connect two electronics products so that when one product is triggered another product is turned on.
I have a small reed switch alarm, with its own power, and when this is triggered i.e. a door is opened I would like it to turn on a small radio, which also has its own power. I figured that if I break the circuit on the radio at the on/off button and connect two extra wires from the speaker of the alarm to the radio on/off circuit so when the alarm is triggered then the radio will be turned on. But this has not worked.
So does anyone know if there is a general rule where I need to match the radio on/off circuit amp, volt, etc? And if so what components do I add to the wires coming form the alarm speaker?
Thank you.
