Hello All,
I'm working on a project.
To make a LED turn on using a photo resistor and a relay. The LED is supposed to turn on when there is light. But how would I do the opposite? When the lights are turned off the LED will go on? HELP
Basically the whole class has been trying to do this and no one knows what to do. Could you guys explain or draw out something I can use as a guide?
Thanks
