I am talking about these - http://a.co/fsI51TN
I am working on a simple "binary" project. When a button connected to the transmitter is pressed, the receiver toggles something. Is a microelectronic really needed? For example, if the input of the TX is high, will the RX output be high?
Thanks in advance.

I didn't see anything in the tutorials about NOT using an Arduino. Did you find otherwise?

No, they use automatic gain correction, they adjust their sensitivity to get approx 50% duty cycle. So you have to use a code that the receiver can look for; just turning on or off the transmitter over longer periods than a few ms will just output ~50%duty cycle noise.
But the transmitter/receiver pairs with PT2262 and the other one can be used without an arduino.
These TX/RX pairs do not need an Arduino.
If you would have googled
433 Mhz without microcontroller
you would have found that the first hit describes how to use the cheap 433 MHz radios without a microcontroller. Imagine that. (Some extra hardware - encoder/decoder - is required.)
