I just posted in your other thread, but the whole thing has been deleted. Whoever did this, thanks ! Very nice.:mad:

Please provide more details:

1. What's the purpose of this project? Demonstration or real world application?
2. Does the ambient light vary or is it more or less constant?
3. Is the components you mentioned all you have? Can you make a detailed list?
4. Can you buy other components?
5. What's the distance between receiver and transmitter?
6. What do you want to control?
