How can i do that.I need full description or circuit diagram.
Any help is highly appreciated.
Shine a laser pointer on an LED that has another LED connected to its leads. The second LED will light. Amaze your friends.
I wonder if it is working..Marks256 said:Will that really work?
yes it will, LED's act like solar panels when you shine light onto them, so hooking one led to another and shining a laser at it will work.Marks256 said:Will that really work?

a 3mw laser would probably just light the led, but not very brightly. i don't know for sure because i have only used a 30mw and 20mw green laser to do itHero999 said:You probably need a pretty powerful laser though, I don't think a 3mW laser pen would be enough to light a standard red LED.
