Hi everyone! I'm new so be gentle please. I'm looking to create two projects for fun using arduino. I just bought the starter pack and am working my way through the various projects in them. I have come up with two myself I would like to accomplish, but need guidance with hardware slection. (Coding will come later).
Project 1: I'd like to activate lights by setting up switches in series. I would like to dress up knife switches to use reed switches instead (for safety reasons). Placing a magnet in the handle and a reed switch either at the top or bottom of the base, the knife switches will need to be placed in a specific up or down sequence to turn on the lights. I'd like 5 or 6 of those. My problem here from what I can tell is that the lights use a much higher voltage than the reed switches usually can handle. Is this a case where I would use a mosfet? How would I complete the circuit using the reed switches and turn on the lights? The lights by the way would be used to light up a whole room, so no small LEDs. One idea I had was to program the Arduino to send a signal to a relay wirelessly, but then how would I provide power to the lights if they have to be plugged into an outlet?
Project 2: This may be similar to the previous project. I want to have candles placed into a candelabra and light up using an LED. This part I'm pretty sure I can do using a reed switch, 9v battery, and placing a magnet in the candelabra. I then want people to blow out the candle. I'd place a microphone near the LED to pick up them blowing it out. The part I think I need help on is how to send a signal wirelessly to a lock that would open up a door. I'd want the candles to be blown out in a specific sequence and the receiver to determine if the sequence is correct. That bit is coding which I can figure out later, right now I'm more interested in what equipment I would need to make something like that happen.
Let me know if more information is needed. Apologies if so, I'm still figuring all this out. I appreciate the help!
Update Just found this great video about controlling high voltage using a relay
