so i have an Arduino nano and was wondering if there is a way/command or something to take in an on-off signal and translate it thru a nano to High/low value?
newbie here
Perhaps, if we knew what the on-off signal was,
it's from a 433 MHz module. the transmitter-receiver thing.
Then that will be in a message sent form the transmitter. What is the message and what part is the on-off?
One Channel Transmitter and Receiver with 433Mhz RF module - YouTube this video but i want to use the arduino input instead of the led.
A controller understands 0 and 1 as distinct primitive values. Everything else (true/false, HIGH/LOW...) can be defined at will.
On/Off mnemos can be helpful e.g. with switches of unknown/alterable connection to an input pin. Left/Right or Fwd/Back with motors...
Capitalization as you like it. Obviously I'm German 
Then you will need a program on the transmit end to send the appropriate message and a program on the receive end to get the message and do what you want with the message. Two Arduino boards and two programs and two power supplies.
What is the voltage across the LED? On voltage=. Off voltage = .
