Breadboards & Radios
You are currently reading a thread in /diy/ - Do It yourself
I previously had no experience at all with wiring, electronics, breadboards, ect., so I've been learning slowly through experimentation and online stuff
So pretty much, I bought a breadboard kit and some 433hz Radio transmitter/receiver pairs. My goal was to use the little transmitters to send a simple signal when they were powered. The signal from each transmitter lights an LED connected to each receiver.
I've learned that this isn't that simple. Do I need one or two Arduinos? Can I just do some simple analog signals or something? It only requires a YES/NO signal so I don't see what the problem is.
If you just want an 1/0 Signal use digital signals. Analog Signals are also for other statuses, between 1/0.
433 Hz is not radio frequency. You don't use LEDs to send radio signals, you use antennae. You don't need any arduinos to do something like this.
What exactly are you using to attempt to send a signal and what exactly are you using to receive it?

I know LEDs dont send signals. I want the LED to light up when the receiver gets a signal that the transmitter is on.
