VirtualWire Library, for very cheap wireless communication
2/10/2012An RF Module (Radio Frequency Module) is a small electronic circuit used to transmit and/or receive radio signals on one of a number of carrier frequencies. RF Modules are widely used in electronic design owing to the difficulty of designing radio circuitry.
Arduino Basics: 433 MHz RF module with Arduino Tutorial 1
Hi, I’m doing a project on locating parked vehicle using RF module and arduino. Can you help me on coding? Reply. a real time clock and an LCD display and I send the measured temperature and humidity values through the RF transmitter to the indoor unit …
Arduino Playground - GPS
I'm using the 3715 RF arduino modules and a hc-sr04, and i'm trying to send the distance i get from the ultrasonic over to the arduino with the rf recieving module but i get something like this: Stack Exchange Network. Transmitting Variables over RF. Ask Question 0. 1.
How 433MHz RF Tx-Rx Modules Work Interface with Arduino
Decode 433 MHz signals w/ Arduino 433 MHz Receiver it I have managed to set up rcswitch on an Arduino Mega and wants to decode a signal from a remote to control some rf sockets from the Arduino. In this tutorial I ll show you how to use an Arduino to decode signals from RF remotes, and re-send them to remotely control some mains
Arduino RF Send and Receive 1technophile/OpenMQTTGateway
For the RF modules, we will use the virtual wire library, to send and receive data, while for the display of the received data, we will use the Adafruit GFX and the Adafruit ST7735 libraries to easily update the ST7735 LCD display.

duino uno - Transmitting Variables over RF - Arduino
In this project, the Arduino on Tx end reads temperature and humidity from the DHT22 sensor, combines the two readings into a character string, and send it over the RF link. On the receiving end, the Arduino extracts the two readings back from the received string and displays the data on the Nokia 5110 LCD.
