Hi. I removed two leds(?) from my coffee machine, which determine if a cup is in position or not. One is red, and the other transparent. How do they do what they do? I would like to use the idea in another project, and need a simple diagram to duplicate the action. This projects power source will be 220 vac. How do I determine what these two components are.
Many thanks,
Dion
