RC transmitter modules

Hello everyone,

Could I get instructions on how to build an Arduino RC transmitter controller but one that can connect to a transmitter module like the ones with different protocols which are attached to commercial transmitter controllers.

Like the one in the video

I've tried to get in touch with the user but of course getting in touch on YouTube is pretty unreliable.

There are plenty of instructional videos on how to make Arduino RC transmitters, but not with an option for accommodating modules.

Thank you

I am not exactly sure how to make one, but I think that you might need some sort of module that would enable connection, and usage of a drone along with some sensors to control a drone mapping system. You would also need a powerful IR emitter and receiver.

Did you Google the OrangeRX DSMX?

That's true, but for now I'm focused on how to get an Arduino transmitter to work with a modules.

The receiver on the drone that communicate with these modules attached to the transmitter; connect to the flight controller via a serial interface.

I'm not sure what interface these modules attached to the transmitter connect on... Any ideas? UART perhaps?

I have, but of course the Orange dsmx module in the video is an example.

I need the Arduino to communicate to this Orange dsmx or any protocol module.

The manufacturer publishes nothing? What about this?:

All I really did is Google...

Connector P1 Pin description: PIN1- PPM signal, TTL 5V, 6-12 channels PIN2- Not connected, PIN3- VCC In, 6-18VDC, 100mA PIN4- GND PIN5- for future use

@rossrosh, your topic has been moved to a more suitable location on the forum. Installation and Troubleshooting is not for problems with (or advise on) your project :wink: See About the Installation & Troubleshooting category.

That's crazy, I did too Google. Nonetheless thank you for your effort.
Also I'm a complete beginner... As in, even I have no idea how to connect this to which pins on the Arduino.
But I want to learn, start somewhere :slight_smile: :slightly_smiling_face:

Start where I started... with things I can do.

True.
But then I can do any tinkering/project unless I get the instructions/tutorials, help etc. I can do this transmitter project ... Given I have the instructions. Also the help as you had kindly provided earlier

Well, the instructions for other projects are thousands of times more accessible, so I think that would be a more practical place to start. If nothing else, you would gain experience that would help you with this project.

I recommend Starting with some basic circuits like Programing LED's, then learning RGB's. Maybe a photoresistor, a 7-Segment LED or a Temperature sensor. If you would like, then I can send you some circuit diagrams. I am only saying this, because then it will be easier for you to work on a drone like that, but then again...it is your choice.

Also do you have TinkerCad if not, you should try it out it lets you make circuits, then also simulate then in your browser.

It looks, after as much googling as I am going to do, that those modules take PPM as the input protocol.

So the guy in the YouTube was probably synthesizing a PPM stream after reading the joypots and switches.

This seems to be what makes that DSNX transmitter JR Turnigy &c. compatible.

So google is your friend, again - PPM by Arduino has certainly been done far past rare and medium-well.

Thank you, that would be great too :slight_smile:
I do need to be pointed/guided to the whichever direction, considering my level in tinkering.

But at the same time with this drone project/attempt, I would like to be pointed to instructions which I can simply replicate. I believe that it may take a considerable amount of time and level of difficulty for me untill I figure out for myself.

I did get to finding out about the interaction being PPM (and if that was a serial interface).

I came across this post Generate PPM signal with Arduino | QuadMeUp

But ... It's Greek to me
I wouldn't know where to start😅

I told you where to start, in reply #9. :slight_smile: Then someone pounded the nail all the way in, reply #12.

If you remain fixated on completing only this one project now, you will just frustrate yourself.

Well that page you linked is a place to start, and so would be several many other pages going over the same territory.

So I'm with the others advising you to slow your roll if you aren't at a place in your journey where such a page is what and all you need to proceed apace.

If you must, try really looking at that code, and some others that do the same thing perhaps a bit differently, and use your best common sense to try to understand.

Messing with this stuff on a cut-and-paste basis will be a waste of time at best and is potentially dangerous.

I have been using Arduino for years to the point that I can make some simple led or transistor modules off the top of my head. If you are going to do this, then do it by all means. But if it means that you wont be able to comprehend how you did it, the it is basically all in vain. If you would like some simple circuit diagrams, please contact me. I think that most of us here with lots of experience are saying that you shouldn't do this yet...it's not to wear you down, but to help you in the long term. We can make it for you, and code it for you, but there is no fun in that. The fun comes when you solve mysteries, and complete it yourself, and it is okay if you need help along the way: that is what the forums are for. But my point is that you can ask questions in the forums, but not a how to sort of thing where others do everything for you. Again, you can do it if you want, but there are lots of reasons behind what me and some others are saying. there are some Arduino starter kits for about 20 bucks that you can buy for some basic sensors and an Arduino Uno which is the easiest to start with.
