- Learn how to use cheap 433MHz radio transmitter and receiver modules to send data between Arduinos, such as might be used to create a wireless puzzle prop "beacon" that can send messages to trigger remote effects, or be triggered itself from a control system.

Once again you have the solution to my problem. Remote controlled flashlights are practically in the bag. Thank you!
Excellent tutorial and dissemination of information.
Gosh, you had been my prof at university. You explain things in a way that is so easy to understand. Thank you so much for moving the clouds!
How can I fall in your love?
Is there any backdoor or Window?
Did you understand the receiver code?
Thanks for this great channel. Really looking forward to the projects you come out with in the future.
Really nice video and graphics. Thanks regards Chris
I enjoyed this video that you went into great detail. Thanks for sharing. I'm going to do a project that detects the distance between two devices, and then sends that distance to the database for storage. I'm wondering to have some guidance about hardware and software.
Sir is there any way that you could make a video on the 433 MHz transmitter receiver module circuit explaining circuit and the components used.
Is it possible to use a receiver to pickup a signal from a remote control on the same frequency or does the receiver and transmitter only work with each other?
I was trying to make a same card of mine rather then buy from market since it has all passive components, other then one tune-able inductor(green one in middle ) so can you tell me how to tune it for best reception? or if i have purchased one how do i know it is calibrated to get best reception so i dont need to tune it further?(since sometimes it is not glued to lock screw position)
Thank for your sharing, I don't know if it is possible to use stm8 to communicate, have you tried it?
Hi. It's possible to make rs485 communication over wi-fi. Transmitter and receiver rs485 ??
Have any exemple circuit ?
If i apply power to the transmitter will it transmit a noise on the frequency......like a beacon or does it need programming? Thanks
how much distance i will transmit signals
So nice thanks sir
Hi,
Nice video!!! Im currently working on a similar project. Got a few question regarding the transmitter/receiver.
Is it possible to use multiple transmitters on a single receiver?
What is the power consumption of the transmitter?
Can I use a coin cell battery to power the transmitter?
really? he said it in the video
yes coin cels are also good
Where can I get a transmitter and receiver for 700Mhz-800Mhz?
Can the transmitter send out different signals 20 different signals and the receiver give 20 outputs ? Or is multiple units required ?
What software did you use to make the schematics? It looks like tinkercad, but not quite
i did try them both without Antenna and i did put them next to each other but i didn't get any signal, should I connect an Antenna ?
can you trans voice over this type of module
i am using 20 pin encoder and decoder. but i don't know how can i connect all stuff. please i need help. my encoder and decoder is MK5035 N00.
Is there anyway you could do a tutorial with a raspberry pi 3? I am working on this project and have tried alot things but i cant seem to turn them on. Im sorry if this is a silly question but are those antennas necessary?
The antennas are necessary. Otherwise the modules will only be able to communicate if they are directly next to each other. The antennas are used for increasing range.
Is it possible to transmitt electricity from these ...?
Could you use two of these as transmitters, sending messages to a robot with a receiver, to create a positioning system using trigonometr and the time taken for each message to arrive from the anchor/transmitter?
You _could_, but you'd need to have a very accurate timestamp synchronised between the devices, or else a multiple roundway-trip at which each device records their own timestamp, and then compares that to the time at which the response is received back.
how to multiple RF transmitter and receiver used one place????we want to unique transmitter for unique receiver how it is possible for multiple RF communication Modules
Could you tell me the connections for an Arduino Mega 2560?
I tried it with my new rf reciever but it doesnt work
Hi. Does the receiver's digital output merely mimic the transmitters digital input state? I intend to use one on a Microchip PIC based project to syncronise three close proximity circuits.
use a ht 12e and ht12d encoder decoder ic
Ķ
I have the same but without resistor
Hello sir.. i have a question. i want to make a remote control servo system with arduino. Is it support PWM signal ?
If yo can Tx an integer value then that could be your PWM value.
honestly surprised ur not more popular
i am interfacing this RF module with stm32 but i didnot receive the exact data which i sent.
can u plzz help me to do this
How detect gps tracker or block signal ?
How to create interference to a hifi (mine obviously....) with a 433 mhz module?
Most hi-fi/TV remote controllers use infrared - are you sure yours is 433MHz RF?
@@PlayfulTechnology No. But I want to use these two modules to achieve this function for other uses. These 433 mhz pcb only act as a conduit.
Maybe I missed it, but where can I access the code for download? The receiver code is hard to take without the ability to study it separately from the video.
this tx rx dont need anycode
Hi,
TNX for Video. I want to transmit data between CC1101 Moduls with STM32 F446re. I sent data randomly but in Receiver i cannot get true data. can you say me , what can i do,please?
Can i use these modules in walkie talkie circuit?
I also had that question.
Yes , you cannot use it in any talkie walkie of your choice.
can v use this for wireless water level indicator?
Sure - you can use it to transmit any arbitrary data - so sensor readings from a water level/temperature/speed/light/anything really!
@@PlayfulTechnology Thanks!
for those of us who don't have a digispark, it would have been very helpful if you had said what the vcc voltage was.
Why dont you look up the value for the voltage? It's all over the RF space on the internet.
@@walshrd And much easier for you to send me to google than to just give the answer. Some teacher.
@@youpattube1 Well, why didnt you just look it up? That's what most everyone else would have done...and we would not have had this stupid conversation.
@@walshrd That's backward thinking. If he had provided the info, no one would have had to look it up and we wouldn't be having this dumb conversation. But I'll give you the last word.
@@youpattube1 Oh. When anyone watches a tech video, it's reasonable to expect to gain some information. Having the code is key to understanding this. Why must I search for it? Is the video just a tease? I could have done a search in the first place and have avoided this video and this DUMB conversation with you.
maximum distance?
.depends on transmitter voltage that you apply on
the more voltage , the more distance.
take care of maximum voltage from datasheet , lest you should damage it
can we send PWM using this module ?
Sure - you can encode any arbitrary data - string, int, float...
I think there must be some good and bad RF modules available, I bought a pack of 5 TX and RX from a well known on-line supplier. None of them work. I know it's the modules as I bought another pair from a different supplier and they worked fine. BEWARE of imitations.
Even though this was filmed at the end of 2017 I can still tell it's from 2017 if that makes sense
No, it makes no sense.
What is a "prop"
Something on the front af a light aeroplane.
That’s crazy .
the rf can calculate sosial distance
sosial is spelled social

People, why are you presenting your talking face for 50% of the time and not focus on what to do with and how the device looks right away? And you can talk in the background. I personally dont like watching your face very much and I am not gonna. Sorry.
Sir is there any way that you could make a video on the 433 MHz transmitter receiver module circuit explaining circuit and the components used.
can you trans voice over this type of module
Read the specs for this cheap transmitter. It transmits character strings. Doe that sound like voice capability?
