In this project I will show you how to repurpose an LED RF remote in order to control pretty much anything you want with it. That means we will have a closer look at the transmission process of the RF remote, read in the sent data with an Arduino µC and use it to control a solid state relay. This way I switch on/off LED lamps, but you can use this technique for other appliances.

Just one minor correction for the terminology at 6:40 or so, the data is encoded, not encrypted... minor difference in words, but huge difference in meaning.
^ this
"Encoding is for maintaining data usability and can be reversed by employing the same algorithm that encoded the content.
Encryption is for maintaining data confidentiality and requires the use of a key (kept secret) in order to return to plaintext."
Yeah so true.
to some the encoded signal would be cryptic :P
I came here to say just that :)
Joonas Loppi me too 😁
New drinking game.
Each addition person who suggests an antenna, drink.
Great video.
I didn't see an antenna on your "el cheapo" receiver. I use these all the time and with a coil antenna, they work fine anywhere in the house.
@@rich1051414 Actually, that isn't an antenna, just an inductor. You need to connect an antenna to the ANT via, which can be a 15 cm wire if you don't have a coil antenna.
Thanks a lot for this videos. I always wanted to demodulate and use my rf remote for some of my project and you helped me out today with this video. All your videos are inspiring and useful to me thanks man keep it up.
Great video always enjoy watching your videos 😀👍👍
Thank you so much, for ripping appart one of these rf remotes. I'm also working on a project using them but didn't want to spend the money/ or time to test it out my self... Thank you!
I was impressed with the use of the solid state relay with main power. give me hope for a couple of ideas I had. Thanks 👍
This was AWESOME! Elctronics are so fascinating to me, I wish I had an ability like yours my friend.
Hello GreatScott,
I suggest you make a video on how to better understand a datasheet. Some technical terms like "thermal resistance" and other technical terms that can sometimes be misinterpreted.
a great idea
Uhm.... You do know, that you forgot to solder an antenna to the cheap 433MHz receiver, don't you?
They don't come with one most of the time so you have to cut a wire to the right length and solder it on yourself, or buy a 433MHz coil antenna from ebay too (they are like 50ct)
Congrats on 1 million subs. Your content is great!

Your videos are great, and so is your accent! Respect.
GR8T, Scott. You are the "spin" in our electrons. Thank you.
After attaching a proper antenna as others have said, it also will help to tune the receiver by adjusting the brass slug in the small coil for best range. Most of the ones I've bought have been significantly off-frequency (typically 3-5MHz high). Also watch out for mis-assembled ones. They've screwed up the biasing of the first transistor, saturating it hard. Good receivers can achieve about -100dBm detection sensitivity or better. Bad ones barely make -80dBm. Nice video.

“G3MB-202P”: we pronounce the “minus” as “dash”. Love your videos. Keep them coming.
Searched for this comment, was not disappointed. The hyphen can be called a minus sign, but only in a mathematical context. In chip nomenclature (and general typography?) it's most commonly refered to as a dash.
Technically both are correct, however "dash" is used especially in model numbers, protocols, etc.
Nowedon't
Thanks for documenting your good thinking here!
was going to do something like this but with the RF receiver from an automotive remote starter for a car to basically run a preset weekly schedule in the winter to warm the car before setting off to work, based on an ATmega88, RTC module (for schedule keeping), and a few high powered mosfets for controlling the high current wires from the ignition switch.
Brilliant! (pun unintended). Definitely one of my favorite videos.
I have some motion controlled outdoor LED lights that have a feature where if you flip them off and right back on within about 2 seconds, it turns the lights on continuously and overrides the motion control. If you turn it off for more that 2 seconds, the motion controls are re-enabled. I think I would have tried something like that in your situation. Flip on the switch - both come one. Flip it off shortly and back on and the white leds go out but the colored ones stay on. Up-side - no remote to misplace. Down-side - remote will allow additional controls like picking the color of the leds.
This is such a cool idea
I am definitely going to try something like this on my next project
I think I might use it for lights too
Because I really like radio controlled lights, but they’re so expensive
Well done
Interesting project 😀👍
Thanks for sharing👍😀
What can be done with any old smartphone lying around or it’s motherboard. (Übrigens bewundere ich Ihr Wissen😊).
Reverse engineer it's display port to be able to connect to digital displays and build Android boxes
This reminded me of my LED remote, which natively worked with a cheep heater without modification.
In case you're interested in working with these types of RF remotes and receivers, I recommend the RFXCOM device. It's a bit expensive but well worth it. The support is absolutely amazing, I once had a few devices that didn't work, after shipping them he had them shipped back to me and added support for them within a week.
Please make ultrasonic microphone jammer..
Thx for ur great explanation
Fantastic ideas - thanks for sharing!
Congratulations bro for 1M subscription
Awesome video!!! I love videos like this!!!
I see, now you are becoming a real technician and master of yourself! Playtime off mode, serious stuff is coming! 😊
Gerade zwei Fernbedienung vor zwei Wochen gekauft.
Danke für die Lösung.
Thank you very much. Good explanation.
Thanks for this video :)
keep up the good work bud! - not many negative voltage videos on the youtube
Fascinating... That’s thinking outside the box, so to speak!
Thank you pal :-D I feel your pain on having to use something you didn't want to use after a while in the end. That happen to me now and again too.
That was fun! Thanks.
Great video as always from GreatScott
Do you consider to replace arduino with esp8266 or esp32 and add WiFi control to the lights? Web server on esp or mqtt approach maybe?
Good video. Been wondering how i can controll something with old remotes i have. Thanks!
Thanks Scott
Great project !
then hook it to a raspberry with something like domoticz and homebridge and you've got a perfect system !
A pi running mqtt broker, with Homebridge ( for Siri and Apple app) and gbridge (for google home app and assistant) is my favourite setup 👍
extremely interesting!
Well done and very very good. Superrrrr
If the vids were not all sponsored, I’d subscribe with Patreon.
Nice vide as always! I was hoping why aren't you using a SSR while watching. It turned out you used it :) Nice!
You are good teacher.
Thank you :-)
I love that you're still using Windows 7!!!
LOL he won't be able to for much longer
@@cyborgsheep6077 I know. It's so sad
Very good 👍
Nice video 👍👌 Great Scott
Video uploaded 3 minutes ago, your comment 2 minutes ago, video is 11 minutes long. So where disapered 10 minutes? Watch the whole video before commenting dumbass.
@@jakubfrgal7112 bro i have watched full video from my another account
@@_DarkKnight so you watched 10 min video in 1 minute and THEN commented with second account. Ok... I get it
First of, great Video!
I wanted to build something similar with an RF remote I got from some cheap lamps, because I liked the design of it. My problem now is that the arduino doesn't show me that he is receiving anything, although the oscilloscope shows me a data pattern. What could be the reason for that?
Amazing videos. One question though, you always seem to be able to identify IC's on commercial PCB's but most IC's don't list a part number anymore. How do you ID chips just by the manufacturer's markings?
Thank you.
Hi Great Scott,
Great videos, you have become a reference point for me and my friends: “great Scott certified statement”, when discussing electronics.
But I have a question, Ive tried to figure out how these mass produced RF controllers are set up. Do they all (or at least a large quantity) have different codes? 24bit should give us ~16 possible integers, which gives us a large variety of different codes. So it is fully plausible.
What would your gut feeling say?
Thanks!
I was wondering if you could do something on zero voltage switching
Very awesome.
you could use high gain antenna for rf reciever.
Hi, nice job. I didn't understand how did u wire up the SSR with switch to control the LED individually. Is it possible to turn ON using switch and turn off using RF remote. Thanks for the video.
inspiring, thanks
superb
Great practical project! But don't yellow and pink buttons turn LEDs to yellow and pink at the same time with turning the lamps on?
Such a great idea to reuse the existing remote. I think it would be better to have "On, On" as well as "Off, Off" toggle the output. That way you can switch it on and off without also changing the RGB LED colour.
I bought some cheap RF mains power plugs from LIDL which I can control using an Arduino and a 433Mhz RF module. Range is good. I plan to use this to power on/off my 3D printer using a Raspberry PI (already using a PI for OctoPrint).
I hope they are 3.3v compatible!.
Take the RXB14 receiver for long distances!
rxb6 is better
Nice, a new Video!
You should revisit this project controlling both GU10 spotlights and RGBW led strip with an esp32 and Home Assistant!
big project
I've been playing around with the Nano for some time doing lighting and effects for scale models. Since reading about decoding remotes with an arduino, I've been wanting to try it. I've uploaded the ReceiveDemo_Advanced example to my Nano and made sure it worked by inserting the Serial.println("Hello World!"); into the code. It works, as the serial monitor shows me a continuous stream of "Hello World!" on its screen. Next I purchased a 433Mhz RF Module Receiver and Transmitter Remote Control using the supported EV1527 chipset, hooked up ground, Vcc, and a connection from data pin 0 on the receiver to pin 2 of the Nano. Finally I paired the remote with the receiver and have confirmation by the receiver led blinking every time I press the remote button. Everything looks fine and compatible, yet when I press the remote, I get nothing other than "Hello World! on the serial monitor window. By all accounts I should be getting data from the receiver on pin 2 on the Nano appearing on the serial monitor, but I am not. Not sure what I may be missing. Do you have any suggestions? Thanks
perfect...video
The amount of time setting up lights for someone who already has all these electronics skills...don't even want to think how long it would take me since I know very little. I might figure out how to view the signal with an oscilloscope after about a week of messing around. You know, after I order an oscilloscope.
Great video, if you don't mind me asking what happened last weekend?
you are the best!
Those modules you have for the 433MHz RF ASK modulation receiver are very common and dirt cheap on ebay/aliexpress ... but they Need an antenna if you want to have some range ... A small helical antenna would be enough. The antenna can be made by twisting a thin wire on a screw and get eh helical shape we need.
good video.
btw, you can avoid relay sparks/arcs by connecting a 1uf ceramic capacitor in series with a 10-100 ohm resistor, between relay contacts.
or a 1uf electrolytic capacitor and a schottky in parallel
the solid state triac also has a snubber circuit. No idea why he would skip it for the relay. Still triac one should be more reliable.
Really nice job, dude! 😊
Too bad the receiver module you got wasn't that good. 😕
You are excellent with electricity!
Thank you
@@greatscottlab You are welcome!
👌nice video
Hey Greatscott! Great video, but I wanted to ask you something. Is it possible to build an RC car with an RF controller? I watched your hacked video of the tv remote and was inspired to make something myself
Crazy smart!
Really nice project but why do you use microcontroller with so many pins when you need only 2, cant you use attiny85 instead?
You are very smart!!!
Will you be also looking at EnOcean 866MHz wireless electric smart home switches? German Eltako have great variety of them (though they are expensive)
Can You do diy or buy project on garage door remote control? Ty
Do the leds flicker? If so, would a big capacitor stop the flicker?
It would be extra cool if you built a module that took in binary commands from the light switch (turning the switch on and off in a particular pattern) to selectively turn on the main light, RGBW LEDs, or both.
I learned some thing new and usefull
i was having the same problem with my ceil but could fix this by buying a 3 color led lamb which changes it,s color by turning it on / off and took it,s circuit and connect each stage with relay and hooked each relay with the light source I want . like that I could turn of/off any light or even both for around 10 $ :) hope this solution help
Nice
Hy scott i did simular thing to my end thasis but i wirted all the code and was atmel studio Put PID in the light to sense the room how much light is in the room i used 4 sensors (you set a light value and the lamp trys to light the room that value)
Can you do a video on DIY RF amplifier circuit?
Good video! But, is there any reason you're using rigid wires? Recycling? If not, I don't think they are a good option. (Also the antenna and the encryption)
@GreatScott! Can you do a tutorial on how a transistor works please? I really want to learn but I can’t find any tutorials that explain it well.
Were you suggesting you’d replace the ground with a live at the start?
Ludic Science also advertises JLCPCB. He called it GLCPCB for years, until I corrected his English.
So I am not very keen on electronics and have to ask. Can you turn this into a remote control for a TV? Not many functions needed just on and off. I understand that there are a lot of dependencies on type of tv and remote. Would this be possible at all?
Do I have to build this too? Like I dont have enough projects already, lol
Wouldn't adding an antenna to the receiver help in increase in its range?
Yes
I don't trust ssr's either because whenever a bulb fails it can take out the triac which is very common in dimming circuits.
i’ve done a similar thing to control my whole room’s electrical devices and it’s been working with a mechanical relays for over 3 years now (: .. so i don’t think the SSR is necessary .. anyway, good job Scot
You have a 3 method to extend the 433 receiver first make 17 cm antenna one fourth of the wave length second use more powerful Arduino like uno connect with 12 volt the Arduino will convert it to 5 volt and connect the receiver with 5 volt from Arduino ... Or you can adjust the screw on the receiver ...this will give you the maximum ringe for the future projects
How about making an update to it.
Use the mode to turn on and off but use the same method with the next button along and turn it in to a mode where the colour buttons match a specific GU10 lamp and turn it on and off as desired to mower lighting to a few lights.
super easy
