The RF Transmitter is only connected to a push button while the RF Receiver is connected to an arduino. How does the arduino detect that the receiver has gotten a basic signal in code? Can I put that basic signal into a variable?
fairly new to coding arduino and just making this project for my brother
That depends on the receiver. Some receivers for use with a push button have relays the close when the remote button is pushed.
That depends on the receiver and the signal. Please post links to product pages for the transmitter and receiver.
Hi @windowsannn,
welcome to the arduino-forum.
I'm pretty sure that you agree and will follow the way how to solve your problem mimimum 200 minutes faster.
This requires to invest 20 minutes of your precious time to read how to speedup solving your problems.
Directly after registering you got presented informations how to speed up solving your problem.
You should really read it.
best regards Stefan
MX-05V for the receiver, and MX-FS-03V for the transmitter, I got them off a kit from a local store
To quote from a description of teh modules that I found on line
The transmitter consists of a single digital input pin that, when pulled high, will cause the transmitter to continuously transmit a signal at 433MHz. Conversely the receiver has a single digital output pin that is high when a signal is received
You will be able to detect the change of state of the pin from LOW to HIGH using digitalRead() and can put the state into a variable
There are even libraries to help
Now that I think about it, yeah, thanks for the confirmation
No. Steady state transmissions are ignored by the receiver.
See the tutorial linked in post #6.
