In today’s episode, we’re going to make a project using Diodes and Logic. Karen wants to build a skylight where there four LEDs, a white one for the moon and three colors (green, blue, and purple) for three different clusters of stars. It will have three switches.  If switch one is on, then the green stars and the moon will be on. Blue and purple would be off. If switch 2 is on then the blue stars and the moon will be on.  Green and purple would be off.   If switch 3 is on then the purple stars and the moon is on.  Green and Blue would be off.   To make this happen we’ll need some diodes and to draw out our circuits to see how we’ll have to wire it up, to make it work.

    Hello Karen What was the program you used to make the circuit? BTW I love watching The Learning Circuit it helps a lot. Gary.

    I do all my board layout planning in Fritzing. They don't always have all the components I use, but sometimes I can find them online to download and add.
