How 433 MHz RF Module Works & Interfacing with Arduino

In this video, we will be learning about the 433MHz RF Wireless Transmitter and Receiver Modules. We will also learn how this module works and how wireless communication occurs between them using Amplitude Shift Keying (ASK) Technique.
Finally, we will learn how to use this module with Arduino to transmit and receive data packet wirelessly. And best of all, these modules are super tiny, allowing you to incorporate a wireless interface into almost any project. The transmission range can be increased by increasing antenna length. The antenna length should be 69 cm but such a long antenna is not feasible. So a 17cm antenna can be used.

Thank you for making easily understandable video. Thanks a lot Man

[@danelaw1902]

Very clear and useful instruction

[@tenlittleindians]

You kept the video short and to the point making it easy to understand for those of us with basic understanding of FM radio. Thanks. I noticed you forgot the link to the source code but anyone that wants to duplicate your experiment can pause the video and read the code off the screen if their monitor is bigger than the phone I'm watching your video on.

[@HowtoElectronics]

Thanks for the support and appreciation Sir. Thanks for notifying about the code, I will be adding link soon. 😊

Good tutorial, is it possible you can make a video about how to build a wire cable tracer and explain why and how it works?

[@shaikafzal2454]

we can use it without an antenna
and it is working great vide

[@pavankarthiknvs934]

Nice explanation. Can I know whether this module works without an Antenna connected at both transmittor and reciever ? Is Antenna mandatory to work with this rf module ? Thank you in advance.

[@devrajput2439]

Can you tell me what the current consumption of receiver module when ideal ON but not receiving anything?

[@dannapurnad3930]

Hello sir , Can I give only connection only VCC , DATA , DATA , GND on one side in case of receiver

[@kpinnovations6613]

How can I make both tx and rx communication unique so other rf signals and remotes is not affect the communication I tried this but when I was push any rf remote button the receiver stops communication or take wrong data

[@fadyqmr2991]

Hello sir
Can i connect two transmitter and one receiver such that one receiver reads data from tow transmitter at the same time?

[@vadlurivarun3519]

Can please provide the code .MY buzzer should on .When i get the transmitter signal off with serial print "Message Not recieved".Please sir.

[@its_just_rami8164]

I'm new to arduino and therefore this, but may I ask if there is a way to send a different signal every time, like after 1 second, a signal is sent, and then after another second, another message is sent. The signal can be binary, and arduino changes it by itself, like first message is "00000", and like second message is "00001". Basically the arduino will simulate something like a rolling code with the algorithm inside the arduino itself.

how to transmit the float numbers and receive it any blog please suggest

[@moncifelkalai8115]

hi can you tell me how can i use infrarouge and lcd with rf module

[@xxDeath99Starxx]

Would the 433 MHz RF receiver work with any 433 MHz RF transmitter? so you can buy a 433 MHz RF remote and it would work once you decode and stuff?

[@ashutoshmithari5155]

can you do the proteus simulation of this because its not workin for me(simulation)

[@-thehindu]

can i use another pin for data in receiver end arduino
3,4,5,6,8,9,10,11 these pins used for PWM in my model
so it is not possible to use 11 pin for data
can i change it to 12 or 13
or into other pin
any suggestion plz??

[@frontier9]

Good explanation but - did you plug the arduino into the power rails of a breadboard with headers? That looks fully wrong ... i mean nice to sit it there but ... ugh

[@eastern815]

Hi sir, may I change the pin12 to another pin as a transmitter?
If I could, how to rewrite my code in arduino?

[@shiyamprakash6545]

simply go to the line in the code which says '12' and change it to ur choice pin and don't forget to give proper connection according to the pin 👍

[@astrospacenomy141]

Very good explanation of the code I have watched multiple videos but yours I believe was the best, most inf and was straight to the point keep up the great work

[@thisisyourcaptainspeaking2259]

That's OOK modulation, ASK uses 2 levels of carrier to represent logic 1 and logic 0?

[@darkblender1114]

I use the same module in my project. But it did not the send the data even 1 m distance why my range is so short. I try long 17 cm copper rod 30 com wire. Short wire, long wire more then 3m long but still it work work only 30cm or less from tx and rx circuit board. Also try 9 to 12v on the transmitter side but still unchanged range.

What if we did 0 in delay

[@kabirsharma4820]

Hey, great video..
I m trying bidirectional communication using these sensors.
I have a transmitter and receiver on remote and a transmitter and receiver on robot.
The robot will send the battery voltage to the remote, (only if the voltage is in acceptable limit the remote should work), then the remote will send command to the robot to move (forward backward sideward etc).
I m doing this using arduino nano but bidirectional is not working.
have you tried bidirectional communication, is it working?

[@HowtoElectronics]

May be you can use NRF24L01 for bidirectional communication. Using RF Module is not a good option.

[@kabirsharma4820]

@@HowtoElectronics Thanks very much for suggesting this. This looks promising. I have checked tutorials on your website, i will try this for bi-directional communication.
