Replacing LED with Flashing LED in a circuit
I am currently building a FRED Photopopper (see circuit diagram at http://www.robotshop.com/blog/en/files/FRED1_3.GIF) but instead of using flashing LED can I use normal LED? I don't get what is the difference between these two in the circuit. If the FLED cannot be replaced, is there any equivalent circuit for a FLED?
