The rc-switch wiki has connection diagrams for both the transmitter and receiver. Most RF controlled devices should work with rc-switch, but if you want you can open up the remote and check that the encoder chipset is on the list of compatible chipsets.
Upload it and open the serial monitor. Hold your remote near your receiver module and press a button. The Arduino should decode the signal and print the results in the serial monitor. This is what I got for my remote-controlled mains switch when I press the button to turn channel 5 on:. The LXA-R4 uses a 12 tri-state bit codeword comprising 8 address bits followed by 4 data bits. My mains switches can have up to 8 addresses with a separate on and off command for each. By pressing every button and decoding the signals I worked out the codes for all the addresses and commands:.
The EV chipset in my garage door remote uses a bit codeword comprising 20 address bits followed by 4 data bits. The codes I got from my garage door remote are:. Note the pulse length has to be manually set because it differs from the default pulse length for Protocol 1. For your device you could create a similar function, or just send the raw codes. Here is the code which opens and closes my garage door simulates button 1 every 10 seconds.
It also flashes the on-board LED to indicate a command has been sent. The transmitter module seems to have a range of several metres without an antenna.
Include control of IR devices e. TV and air-conditioning remotes. To improve the illusion, the schedule could be varied randomly. Port to Raspberry Pi rc-switch has a rpi port. I need help. I am doing a project in my M. I want to know about Arduino, I mean after installing Arduino, gnuradio after that I did not understand what to do?
Question 2 years ago on Introduction. How can I find out the best pulselength for the receiving side? Question 2 years ago on Step 4.Use the Microsoft Remote Desktop app to connect to a remote PC or virtual apps and desktops made available by your admin. The app helps you be productive no matter where you are.
Getting Started Configure your PC for remote access first. How could Microsoft tolerate that its own product is seriously better on a competing OS than on its own OS!!! I can't even guess what keyboard MS Remote Desktop is trying to use.
Luckily the old remote desktop connection mstsc. Why is there a much better Mac Remote Desktop than Windows? I like the Mac version you can change the screen size, have multiple open windows, share you drive etc.
This seems so tailored to tablets that it forgot that Windows 10 is still also a desktop OS. How can you fix this. Not sure why you can't make this better as you wrote the OS and the App? Microsoft has made great progress in the app Just please continue updating it. Works for about an hour, then freezes. Not worth it. What is the difference between this one and the one that says "preview"? Missing multiple monitor support is a big negative. My host has multiple monitors, and I want my connected desktop to all span those monitors in fullscreen mode.
The ability to reuse the login really helps me to manage over 20 instances. I need to use multiple logins depending upon the usage. I wish this had a tree structure to group the servers or at least an ability to resize the icon size. Translate to English.

You don't need to open the outer casing of this smart switch.IHC is a super app you can enable all your home appliance smart and control them from any where at any time. You can interact with smart hardware via your mobile phone easilyand get interoperability between intelligent hardware. Note: continued use of location services in the background will reduce battery life. It does! Why did I give this 4 stars? I use old 32 inch TVs as monitors and the buttons are in the worst places.
I lost the remotes long ago, but with this app you press a couple buttons and it connects it right to it with most buttons pre-programmed. If you have an Alexa enabled device you can easily teach it the broadlink skill and have her control your stuff just by using your voice.
I was surprised to see so many negative reviews! It often takes quite a few tries and can be kind of frustrating, but that may be more to do with the RM hardware. They could definitely use some polishing, though. That would make this app incredibly powerful. For example, when you click a device, you get a quick pop up menu I want to be able to swap out the channel changer for volume. Customer support has been okay.
Again, fairly confused by some of these other reviews. I bought RM pro and should say it works and could meet most of my requirements. I use it to control my projector, e-screen and TV, and could also connect it to my Google Home to activate scenes. But there are something it doesn't support or has bugs: 1. It doesn't support my LED remote because the remote control doesn't use mhz or mhz frequency. Yes, it only supports these two freqs. If don't use TV template, the user-defined control only list the button one by one and cannot change button positions.
Which means you cannot design customized control panel. Bug If you plug off RM power or temporarily disconnect it from network, all your saved scenes saved in the app before will be all empty, but it is saved in the machine.
It means Google Home still works but tap scenes in app cannot activate the right scene action. Requires iOS 8. Compatible with iPhone, iPad, and iPod touch. App Store Preview.

One of the easiest and safest ways to remotely control appliances connected to mains voltage is using radio frequency RF controlled outlets. Using remote controlled outlets have 5 benefits:. Note: you need to buy remote controlled outlets that operate at a RF of MHz. They should say the operating RF either in the product page or in the label. You can use the preceding links or go directly to MakerAdvisor.
The outlets must be both on the I position. If you plug them to an outlet, you should be able to control the remote controlled outlets with your remote control. This will most likely work with all popular low-cost power outlet sockets. You need to decode the signals that your remote control sends, so that the Arduino or ESP can reproduce those signals and ultimately control the outlets. The library comes with several sketch examples.
This next sketch opens:. View raw code. Open the Arduino IDE serial monitor and start pressing the buttons. As shown in the video demonstration below:. Thanks for doing all of this work both for this project and all of the other projects you do.
Again thanks. I am not seeing any output in serial monitor. Thank you… Hope to see your reply soon…. Can you try it with a new receiver? I have compilation Problems. But all ok. That was the Problem! Now it works. Hi Sara. Regards, Sara. Ciao e buon anno! Articolo interessante, grazie a voi per averlo condiviso. Hello and happy new year! Interesting article, thanks to you for sharing it. I asked if you can also copy radio controls for the garage opening at mhz.
Also, I was wondering if this code can use with nodemcu.I guess everybody knows those remote controlled switches that in their simplest form come in a couple mostly 3 of switcheable devices to plug into the mains outlet and that will receive a plug of a lamp or something and that can be switched on and off by a small hand held device. Using an Arduino or other micro controller instead of the handheld transmitter to switch those devices on and off is the basis of many DIY 'home automatisation' projects.
Still, for the novice it can be a bit daunting to get one of those sets and use them in combination with a microcontroller. My goal in this instructable is to help those people on their way. However, I owe a big word of thanks to Jeroen Meijer for developing a great libraryadding classes for some of the remotes I had and for helping me understand the concept of 'trits'.
Most of those remote control sets work o a frequency of Working with MHz is the simplest and cheapest as the transceivers are ubiquitous and cheap. The MHz protocols often send data back and forth and the transceivers are more expensive and harder to find.
The MHz transceiver sets are also cheap and easy to find but not too many commercially available switches work with MHz Therefore I will focus on the Mhz systems. The transmitters are actually quite decent, but the receivers are crap.
They do work and can be used but dont expect miracles. As most of the people are interested in controlling devices from thei mirocontroller they will mostly only use the transmitter, so the quality of the receiver module isnt that important, but if you want to receive data from say a weatherstation, you may want to invest 1 or 2 euro more and buy a crystal driven receiver.
The transmitters come usually with 3 pins: Vcc, Ground and data. The data pin needs to be connected to one of the digital pins of the Arduino, say pin 7 if you ned to use the receiver, that usually has 4 pins: Vcc Ground and two data pins. One of the datapins needs to beonnected to a digital pin. Most libraries expect this to be Digital pin 2. However, some not all so called 'sniffer' programs that are used to discover the code for a device, expect the datapin on analoge pin A0. Without antenna, the range of the cheap transmitters is really limited.
In combination with the receiver of the pair perhaps only centimeters. If used in combination with a commercially available switch maybe 2 meters. You will need an antenna to increase the range to acceptable standards. For the MHz transceivers this comes down to a straight wire antenna with a length of That will give you a decent range.
With a bit more effort however it is possible to make a so called 'coil loaded antenna' that will increase the range significantly. I have written a seperate instructable about that one.
One of the advantages of the Arduino system are the available libraries. For control of Remote Switches there are basically 6 libraries:. For completeness sake I also mention the Manchester library and the VirtualWire library, but these are aimed more at interArduino communication. The main difference between thosw two is that the RCSwitch library sends numbers and the RemoteSwitch sends protocols.
The advantage of the former is that you can send basically any code without knowing what kind of protool your Remote uses. The disadvantage is that you need to know all he codes for on and off of each device.
