Arduino secure two way communication over radio

I would like to implement a secure communication channels between 2 arduinos communicating over 433 mhz radio modules (to be more precise using the barebone Atmega 326 chips). I know that the lack of resources are a problem with the Atmega chips.…

Wemos D1 Mini using RF with RCSwitch

I’ve bought a RF transmitter and receiver on eBay and I’m trying to get my garage door codes with my Wemos D1 Mini. I’ve downloaded the RCSwitch library, hooked up the receiver to ground, 5v and data to pin D4. Also flashed the sample receiver…

RF signal boosting

I'm working on a quadcopter project. The quadcopter will be quite autonomous, but sometimes I'll need to send some messages to it. So I built a simple, one-way RF communication system based on two simple 433 MHz modules. It works, but when the…

What module can I use for receiving 433.42 MHz transmissions with ASK/OOK modulation?

I am looking for a module that would be able to receive communication in the 433.42 (ch01) range with ASK/OOK modulation. Can someone recommend anything that would work and not be an expensive general purpose SDR module? Long story: I have tried…

How would one send radio signals from Arduino at a non-standard frequency

TL;DR: How would one send a fixed radio signal at 447,54MHz with Arduino? Background: I recently purchased a (receive only) SDR and recorded my garage door fob. I found it sends a fixed signal at the frequency 447,54MHz, which I was able to decode.…

Library to send large amount of data over 433 MHz

I am trying to communicate between two Arduinos using two RF 433 MHz modules (transmitter receiver). I found that the library Wildewire.h allows a maximum of 77 bytes so is there any another library that allows to send a more than that?

Change RF Receiver Frequency by Antenna Length

This may be a very stupid question, but I have got me one of those cheap 433 MHz RF modules for the Arduino. I'm wondering if I can vary the receiver's frequency by simply changing the length of the antenna? Or does the circuit limit the frequency…
