You may also sense the LED status by using Photo diode. It is the best method. Or You can take the voltage across LED. Use a Transistor as a Switch to boost the voltage to 5v.Author PostsLog In Register Lost PasswordViewing 2 posts - 1 through 2 (of 2 total)You must be logged in to reply to this topic.
