1  Using Arduino / Networking, Protocols, and Devices / Read 433Mhz remote's code on: July 11, 2014, 07:53:33 pm
Hi there!

I'm trying to duplicate my garage's gate's remote in a standalone board that I need to mount on my bike, so I don't have to look for the right button in my pocket everytime.
I have a couple of TX RX 433Mhz modules, and I need to reproduce the code.
I know it doesn't use rolling code.
I was told I need to use a logic analyzer to read the code, but not how to use it.

Can you please describe me how I should use the logic analyzer in order to get the code, and how to reproduce it through the TX module, please?

Thank you guys, you're awesome! =)

Hey there!
I've been quite busy these months but now I'm picking this project up again.

Got the 433 MHz TX and RX modules, now I need a way to intercept/read the remote's signals in order to reproduce em via the TX module.

It seems the logic analyzer is mandatory, so I think I'm gonna buy something like this one. Will it do the job?

I'm sorry but I have to ask a couple more things: is there any other material I'll need in addition to TX RX 433Mhz modules, Logic Analyzer and Arduino?

How do I use the analyzer to read the signal emitted from the remote?

Thank you guys, you're awesome!

Ok. Thank you very much for your help! =)

Thank you for your reply.
What if I already bought a pack of 1K LEDs and I'd like to use those?

Hi all!

I'm creating my first standalone project using an ATmega328p and 2x 74HC595 shift registers.
What I need to do is control 12 LEDs that will be visible through some holes in a shell.
I'm new to electonics and I'm looking for some cables that I can solder on my board on one side, and attach to the LED's leg on the other. Is there something like that?

Thank you all! =)

To give you a better idea I attached a sketch

I bought it on Ebay =)

This is the battery and this is the module

So is this correct?

Battery+  >>  IN+  >>  OUT+  >>  Arduino5v >>  OUT-  >>  IN-  >>  Battery-

thanks

Ye, sorry, I mean I bought the whole LM2596 module. So I don't need the L7805.

I just didn't understand that thing about IN/OUT +/-. Shouldn't the ground be only out? I'm confused.  smiley-red

Thank you.

Hi there!
I'm creating my first standalone project that has to be mounted in my motorcycle.
The power supply will be a 12V battery (5Ah 30A), so I need to convert from 12 to 5V.
I bought an LM2596, but since I'm a complete ignorant, does it need the help of an L7805 or it does all the job alone?
Also, on the LM2596 there are IN+, OUT+ and IN-, OUT-, what is the difference?

Thank you guys for your help and time!

I think that too, and I was wondering if since you can write by there, you can also read the code
12  Using Arduino / Networking, Protocols, and Devices / Re: 433.92 Mhz garage gate opener on: January 25, 2014, 08:31:35 am
Ok, then for now I'll order the RD modules, then when I have them I'll try to intercept the signal with the application shown in the thread you showed.

Just one more thing: since the gate's been recently fixed, my father wants to convert that old black plipper (I learnt a new word today smiley-grin) to work with the new gate's receiver, and he said that he just has to go the hardware store where they can read the transmitter code. Now I don't know which kind of code they read, since it can be used to set up those pins, but I'll ask them this Monday.

I'll post eventual updates! =)
Guys, thank you for now!

It has 2 buttons since it's a condominium with enter and exit gates, so I just have to repeat the operation =)

What should I do if I want to try to read from one of those pins?

... the project was abandoned due to lack of help in doing the Processing code ...
well, I don't know Processing, just heard about, but I'm not bad at programming so if you want to explain me what was exactly that project, and what had to be done, I can consider picking it up smiley-grin
if it's a matter of representing the data, I can do it easily with C# that I have a lot of experience with, just tell me where and how to gather these data


... (and me getting a hardware device)
can you show me the exact hardware you used? so I can evaluate it (and if it costs too much it's a point to Processing smiley-lol)

anyway, will this or this be correct purchases?

Thank you Riva for your attachment, I really appreciate it!
I have some questions:

- in your code, you use a sequence of delays in ns:
380,440,700,800,360,440,720,780,380,440,700,800,360,460,700,780,380,440,700,800,360,800,360,460,720,13000

is that he full sequence that the receiver needs to hear or is it repeated 3 times?
cause it's visible a sort of repetition
380,440,700,800,360,440,720,780,
380,440,700,800,360,460,700,780,
380,440,700,800,360,800,360,460,720
13000

but the last line, 130000 apart (that I think it's a pause), is different, why?

- is it possible to obtain that sequence just using the receiver module?

Also, notice the first set of photos I attached: can that group of 5 pins be useful to the purpose?

Thank you guys!

Hi pico, thank you for joining!

Well, I got the idea yesterday when I realized I will have more free pins than I expected on my current project, so at the moment I don't have the necessary hardware. As I wrote to pico, the main question was whether this project was possible (now confirmed I think), and which hardware should I buy, that pico and now Riva seem to confirm to be a couple of RF transmitter and receiver.
My fear was waste 1/2 months waiting for something that doesn't work for my case, and then wait again til April/May to try again.
If you say this is the setup I need, I'll make the order =)
