Hello , this is my first post I know the basics but am not an electronician ,
more of a handyman .
Here is what I want to do :
My door opener has a magic eye ,when the car is clearing the path of the infrared sensor ,
a tiny led comes out faintly illuminated . The led is hard to see .
The led is illuminated by .5 volt ( half a volt) thus few milliamps
Can I use this tiny voltage to trigger a bigger source of light .
The lowest relay I found is 3.5 volts ...
Thanks , Robert
