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.

@omc 5 лет назад

^ 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."

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.

@GRBtutorials 5 лет назад

@@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.

@nevellgreenough404 5 лет назад

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. --N2GX

@LeoDDJ 5 лет назад

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)

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.

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.

@MrEdwardhartmann 5 лет назад

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.

@Explore-Gobal 4 года назад

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

@noggin73 5 лет назад

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!.

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.

@hossamebrahim8195 5 лет назад

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

You forgot the antenna on the receiver. A wire of a certain length is sufficient. At a frequency of 433 MHz the wavelength is approximately 70 cm, so an antenna approximately 35 cm long would be the most efficient. A wire with a length of 17.5cm is also possible. (1/2 or 1/4 λ)

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.

Software Engineering isn't just coding all day everyday. It's more documentation and the relationship with the client. You'll be exposed to program development models, team management, how to deliver what the client wants according to the selected development model and stuff like that, alongside writing your actual code. Electrical engineering is power grids, electronics, plant-based designs( controls and Instrumentation) and communication systems. All of those involve math and programming. Ladder logic, Matlab etc but you need to know the math involved in order to write the code. Computer science is heavy coding but you need to have a mathematical understanding of how code works. Not just write the code, throw it to the compiler/synthesizer and hope for the best performance.
