I have very little experience with designing or building circuits, so I'm looking for all the help I can get. I'm looking to design and construct a circuit to incorporate as part of an interactive puzzle. Its function is relatively simple, I just need it to be able to receive a signal, and light up and LED. There are a few more specifics and qualifiers, but that's the easiest way to explain it. What I would like is someone to inform me of what all components and materials will be necessary, and possibly recommend a place to get them, and then help me with a design of how everything will go together to accomplish my goal. If anyone is willing/able to help, or knows of elsewhere I can obtain this help, please let me know! Thanks in advance for any help or advice!
