How to switch on a 9-33v DC LED light using 3.3v as the 'trigger'? Answered
I have a difficult entrance into garage and want to use an orange 9-33v DC LED as a marker light when the garage door is opened. I would like to be able to connect the marker LED to the 3.3v LED that comes on when the garage door is opened. This is on a timer, so I envisage both the garage door LED and the marker LED switching on/off when the remote is activated.
