Really helpful. I just bought the 8 channel version of this board and I want to use it as an audio selector. ( I know what to do) but your video helped me to understand the capabilities of the board. - Many thanks. Its Crazy that when you buy these things online the manufacturers / distributors don't send any information with the board :-) if they did then probably a lot more people would buy the boards

I am pleased you found it useful. The best thank you for me is to Subscribe and thumb up 👍 the video. Thank you.

Hello, use arduino to be your own King and do anything you want. this module is very limited. Here is $200 Arduino course for free Arduino Step by Step Course (over 100 video lectures) Starts here robojax.com/L/?id=338

Where can I buy one of these controllers? I live in Canada. Are they available with 20amp and 30amp relays?

[@robojax]

Hi, just follow the link for resources in the description and you will see where to get it from. The relay is standard of 10A.

[@veszti81]

Is there way to use the trigger button as a permanent thing? To work the same way as the IR button push? If I want to control lights both way button+IR, I have to keep pushing :) and this not so good... The video was great, it helped me a lot, thank you very much!

[@robojax]

I am sorry for late reply. I was on vacation. You are welcome. I have not tried it but it would be very hard as the IR receiver is connected to MCU (microcontroller) and decoding and control happens inside it. so it might not work.

[@SONUKOL1]

Very super 🥰

[@robojax]

Thank you! Cheers!

Can you give me HEX CODE corresponding to its button

[@robojax]

I don't know. we just press the key and it does the task.

Hi, I am sorry. The link was missing and I just add it.

Please provide code

[@robojax]

it doesn't have any code. Use remote to control the relay.

which code? there is no code. Everything I know is presented in video.

try the seller's on eBay or aliExpress or Amaozn and see if they have code for you.

Sir plz send code [e-mail] This is my male address

[@robojax]

this has remote and that's why there is NO code. why would you need code if you can program it with simply remote? this is the easiest way.

If you absolutely want to make reviews, then make some useful reviews. instead of the junk you do !!!

LOL. what did you expect and not found?
