How 433 MHz RF Module Works & Interfacing with Arduino
67,451
Published 2019-08-04
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
-
Very clear and useful instruction
-
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.
-
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.

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?
-
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.

Very helpful video 👍
-
we can use it without an antenna and it is working great vide
-
good use of google assistant and video is super easy to understand
-
Hello sir Can i connect two transmitter and one receiver such that one receiver reads data from tow transmitter at the same time?
-
Hello sir , Can I give only connection only VCC , DATA , DATA , GND on one side in case of receiver
-
Can you tell me what the current consumption of receiver module when ideal ON but not receiving anything?
-
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
-
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
-
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??
-
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?
-
Thanks bro you help me to understand it
-
That's OOK modulation, ASK uses 2 levels of carrier to represent logic 1 and logic 0?
-
hi can you tell me how can i use infrarouge and lcd with rf module
-
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
