Hey all looking for some guidance on a project I'm working on. Wondering if anyone knows of a component and programming to be able to send 12v of power to something with the push of a button. I have a remote set up with a nano, switches etc with a long range antenna just wondering about the receiving end mostly. I know the receiver would be there along with the battery power but haven't made it much further than that.
Idea/ set up:
-Left switch is power to the whole box, turns on the screen and power to the 2nd switch.
-right switch turns on power to the button
-button sends the signal to the receiver to send 12v of power to the powered item.
-LCD with a power up message(with the left switch) and another fun one or countdown to power being sent.
So far I have:
the parts, box made, the screen, the antenna/ receiver, the lipo batteries, a few Nanos, etc just not sure how to make the magic happen.
This is a quite usual question, how to communicate over longer distances. What is Your target distance? Know that the distance is highly dependant on the environment, the circumstances like free sight between the antennas.....
Perhaps you should see what Nicola Tesla tried in his project to send electric power without wires.
Otherwise, your discussion makes no sense to me. Perhaps a block diagram would help.
Apologies, I knew I forgot at least one thing. The "long distance" is between 250-500 feet and it is a clear line of sight. Not too far but the only thing I've found online wont reach that far.
You mean like WWW.forum.arduino.cc??? Or something else?
I did also take a peek on some other WWW places BTW. I agree I can look more and definitely plan to. I am not asking for anyone to do the work for me by any means. I have the screen, switches and box made and set up already. I am running into issues on the part of sending the 12v with the push of the button. I have found plenty of info on the sending of signals like with the ir remote and items like that but wondering about if there are maybe some components or something I don't know about that might help.
This is also not my first stop. I have looked in a few places for the info but it seems like I am asking the questions wrong so any guidance or even pointing me in the right direction is appreciated.
Sending 12 volt makes no sense.
Using a high energy microwave signal the Swedish railroads was running their ATC system. The microwave beam energised units in the track to dend their information to the safety system in the locomotives but that distance is short, a few feet.
I'm assuming that when you say "sending 12 volts", you mean that you are sending a radio signal via the nrf24L01, which is interpreted at the other end, and a switching device (relay, mosfet etc) applies 12 volts from a battery to the switched item.
That is, in itself quite simple. Start with just 2 nrf24L01 radio modules and 2 arduinos and a tutorial. Your problems come later when you try optimise it all for maximum battery life.
6v6gt yes, your explanation was significantly better than mine stating the idea of what i am trying to do.
There are 2 devices, the transmitter and the receving side. On device #1 i want to push a button that sends a signal to device #2. When the signal is received device #2 sends 12volts to a switched item but only for a short burst. It sounds like i have most of the components i need and will look more into relays, moffsets and tutorials for the set up. Thanks for the info.
