I'm looking at possibly using an arduino mini pro for a project. I would like to know if i can use an rf remote from one of these Amazon wireless relays with a RX rf module possibly? I realize most of the transmitters and sold with the receivers so pairing is not an issue but curious if it is possible and if anyone has successfully made one of these combinations work b/c that is what I need for my project.
I also see one of these kits comes with the 4 button remote so that might be easier for pairing but not sure if it works with arduino?
Not likely. You do not know the exact frequency each of the proposed devices uses. plus you do not know the modulation type for each. There is no Arduino code that I have seen that allows you to see the code being sent by the push button device.
Thanks for that information, it saves me from going down that rabbit hole.
Let me ask you this, what about the option which has the 4 button receiver paired with the transmitter as one kit in the link below. I assume the frequencies are tied between the receiver and button remote to begin with? Will that work with adrunio?
Agree, but I'm asking if this is compatible with arduino the kit that has the remote and receiver. I suspect it would be as simple as connecting the output pins to a gpio input signal on the ardunio?
I'm going to open another thread asking about best options on the arduino model to run running with a battery and code to utilize LowPower library and how that would all work. A lot to investigate and research.
You need to describe your project both in words and diagrams. Try not to design it yet, just tell us the requirements.
EXAMPLE
I want to open a light weight gate when I get within 10 ft of it.
NOT
I want an arduino to read a sensor and activate a DC motor.
Anything is compatible with Arduino if you take the time to build and program the circuit.
What gave you the impression a remote control vehicle was just connecting a wire?
I suspect you have watched a number of The H-Lab videos. They do a lot of work before producing their (very cool) videos. You seem to want a turnkey solution, which are available from Arduino or Elegoo or SNICLO. Posting a wishlist is good for an introduction, but you must follow that up with what you will be doing with the information.
For you... have you programmed any Arduino to blink an LED, or drive a motor, or steer a vehicle, or used an RF transceiver? Present what you have done and you will receive more help.
Based on the reviews of the receiver and those who have it working with arduino IDE without any additional library I think it should work for the intended purpose.
Not sure how the conclusion of turn key or for a vehicle came about but in any case I think i have the answer needed.
Sorry details can not be shared beyond the general information provided.
Not all 433MHz transmitters, receivers and transceivers are made the same. I have four variations. Positively identify your module.
Many of the instructional web sites will have you up and running. I like to reference DroneBotWorkshop.com and RandomNerdTutorials.com for their (usual) thorough explanations of the project as it progresses.
I posted the model already, based on the feedback it just requires the arduino board to listen for input on a digital input signal. Seems straight forward without the need for a library. At least that is what one of the reviewers stated.
Not yet, still in the information collection phase of the project. As the scope grows so does the options unfortunately. Customer is now interested in getting images sent via email which is not too bad but the pro mini does not have wifi so looking at other options with integrated esp32 or not that also support camera but not onboard like arduino nicla vision which has special high density connector which does not allow for extension of the camera. Looking at esp32-cam to see how that might work with pro mini. Scope creep is unfortunate but it provides more options. Back to the drawing board, but i think this module will work for one aspect of the project.
this should lead to a list of hardware and software requirements which can be used to select microcontrollers, sensors, IO controllers, communications, etc
the selected devices can then be tested in individual programs to check for suitability and easy of use, e.g. documentation and support libraries
a prototype can then be implemented to check that the various hardware and software components work together and meet the requirements specification
usually this is done at the start of a project before attempting to make unsuitable hardware meet the requirements!
@Paul_KD7HB - agree, i plan to make a purchase of this and several other components to begin testing once the final design is done. This receiver is just one piece of the puzzle
@horace - you sound like an engineer just like myself. Still in the first half of the V model with conops and requirements development on this project. The non-arduino concept has been designed, prototype of phase 1 is completed and operational, this is building on that, with goal to simplify and minimize using more software based controls. The scope creep is expected as I'm myself learning of the limitations of arduino. I'm pushing away from AI & ML as it is not native to arduino on this one for various reasons so the scope is narrowing down on the options which will ultimately drive the final solution. My own ignorance of arduino capability is partly the blame for some of the scope creep as I learn more I can offer more options to the customer.
With respect to "unsuitable hardware" it looks like this receiver and transmitter combo works, again based on user reviews. As i mentioned this is a small portion of the larger project this was always going to be a driver and requirement.
You should look to other devices , RF Solutions make range of devices that don’t need software and can be readily connected to a micro and make more professional looking job .
When were you going to tell us you are a consultant with a customer?
Why would you need a pro-mini if you have an esp32-cam although one of the newer esp32s with more pins may be needed but since we have not seen a wiring diagram it's hard to say.
