Library for RF remote switches

If you happen to have a second arduino, you could use show_received_code to verify that the arduino-synthesized code is identical to the real remote.An digital oscilloscope or data logger is quite handy in this kind of situations, as you can monitor the actual inputs and outputs of the transmitter and receiver. @DARRELL: have a look at the Retransmitter-example, which simply retransmits a (recognized) received code. For transmission you don't need special interrupts, other than the one Arduino uses for delay().

But that one is standard anyway. Relevant code sniplet, based on the example: #include <RemoteSwitch.h>...unsigned long code; code = receivedCode;code |= (unsigned long)period << 23;code |= 3L << 20;RemoteSwitch::sendTelegram(code,11); This will transmit a signal on pin 11, where receivedCode and period are the values you've already found. @Marlar: "device", "address" etc are arbitrary terms used by the remotes themselves.

RF24: Driver for nRF24L01(+) 2.4GHz Wireless Transceiver

Maximally compliant with the intended operation of the chip Easy for beginners to use Consumed with a public interface that's similiar to other Arduino standard libraries News NOW COMPATIBLE WITH ARDUINO 1.0 - The 'master' branch and all examples work with both Arduino 1.0 and earlier versions. Please open an issue if you find any problems using it with any version of Arduino. NOW COMPATIBLE WITH MAPLE - RF24 has been tested with the Maple Native, and should work with any Maple board. Useful References Please refer to: This chip uses the SPI bus, plus two chip control pins.

Adding 433 to your Raspberry Pi. In this blog post I'll show you how to add RF 433MHz to your Raspberry Pi.

Adding 433 to your Raspberry Pi

Requirements - A Raspberry Pi (ORLY?) I'm using the revision 2 Pi, but if you have the revision 1 board, you'll just need to be mindful of the different pin numbers. As you'll see, the code uses *wiringPi* numbers and these haven't changed between revisions (thankfully!) But be aware that the RF receive pin we use will be BCM GPIO pin 27 in revision 2, and 21 in revision 1. . - A 433MHz Transmitter module. 12 : Allumer des prises à distance.

12 : Allumer des prises à distance

Avant que la fin du monde (un peu tardive), ou une trop grosse cuite du nouvel an ne nous sépare, je tenais à vous offrir ce petit tuto sur le “télécommandage” (ça se dit ça?) De prises électriques depuis le raspberry PI. Nous allons donc reproduire notre tuto 7 “éteindre/allumer une lampe avec le raspberry PI” mais cette fois ci, sans utiliser de fils. Démonstration Voila la traditionnelle petite vidéo de démonstration de ce que nous allons faire : (Un grand merci à Maxime Raynal (dont on peux reconnaître le petit accent chantant dans la vidéo pour son fabuleux montage , ça change de mes précédentes vidéos filmées à la Blairwitch) Quelques screenshots de l’application web évoquée dans la vidéo : Accueil des périphériques, par pièces Espace de configuration sans utilisation de base de données Interface adaptables tablettes/smartphone. Openenergymonitor/emonTxFirmware. Ninjablocks/433Utils. Rc-switch - Arduino library to operate low cost 315 MHz / 433 MHz remote control devices.

There is a port available for Rasperry Pi: Send RC codes Use your Arduino to operate remote radio controlled devices.

rc-switch - Arduino library to operate low cost 315 MHz / 433 MHz remote control devices

This will most likely work with all popular low cost power outlet sockets. All you need is a Arduino, a 315/433MHz AM transmitter (find out where to get one or hack your existing remote control) and one or more devices with a SC5262 / SC5272, HX2262 / HX2272, PT2262 / PT2272, EV1527, RT1527, FP1527 or HS1527 chipset. Also supports Intertechno outlets. Receive and decode RC codes Find out what codes your remote is sending. All you need is a Arduino, a 315/433MHz AM receiver (altough there is no instruction yet, yes it is possible to hack an existing device) and a remote hand set.
