Thank you VERY much for the tip on the other modes. Supplier advertised it as momentary only, so I thought I was going to have to send it back or do a lot of extra circuitry. Brilliant now it's toggle which is what I wanted 😃

[@ashtontheman4857]

Thanks man

[@woolfy02]

That's a really cool project! I don't yet have a use for it but, hopefully in the future. I just had a question about the led setup. The resistors that are connected to the 4 led lights, how do I figure out the correct resistor to use? Will the leds just burn out without a resistor in place? Also, do you know of a guide to setup and to be able to run 12 volts on the output side, instead of the resistors?

[@thalesmaia6607]

Very good. I bought a few units, but some units delatch after sometime. Any idea what can be?

[@robojax]

I have no idea. either the module is bad or receiver receives signal or "assumes" to be receiving signal . of course I assume that your transmitter keys are safe and no one presses any key. or check the keychain to see if buttons are good. sometimes they could be depressed a little and you won't know.

[@Julian44444]

Hi great tutorial, I need to use this for my rc car lights. LEDs , they have a positive/negative wire and the others only have 1 wire.... How can I power it with a 3s lipo (12v) but not burn the LEDs as I believe they are limited to 3v... Thanks a lot!😁

[@robojax]

Hi, and you are welcome. the LED should be either 2 wires which is regular LED or 4 wires which RGB (3 for R, G and B and wone for Ground). if your LED has 3 wires, then you have 2 LED with one common Ground. something like this www.nutsvolts.com/uploads/wygwam/NV_0300_Marston_Figure09.jpg so find the common wire by disconnecting them one by one to see which one turns OFF both and connect that to the relay to turn it ON or OFF. as for powering with 3S lipo, I did not get it, powering this module? it will not harm this. I have clearly explained that this module needs power to operate and it has nothing to do with your LED or other stuff or even AC load that you turn ON or off. I hope this helps you. good luck.

[@davemoore7442]

Greta description of the operation of the device but I doubt the relay PCB tracks have safe clearance from the 12V DC side for use at 240V AC. As a minimum use an RCD / GFI and connect the 12V -ve to mains earth.

[@kevinacar2113]

Good day. Can someone help me, the red light on the module is not lighting up when i press the learn button for choosing another mode on the module. What will i do?

[@rizwanhameed5791]

Also tell us the ics or microcontrollers which are used in the product while product reviews.

[@robojax]

not needed because you don't deal with those. if they burn you throw this module and buy another one because the components are more expensive than the module.

What is the role of jumper if it has four pins 1,2,3,4. What are its modes with it? How to set the modes and operate?

@@robojax thank you for replying

[@deanthemaddog]

Love the channel! I have tried using a similar relay, but it is a 220v trigger and 220v relay. I can pair the remote and the LED flashes and "beep" when done. But when I try to activate relay with remote, relay does not respond, only unit "beeps" ?!? Any thoughts

[@robojax]

Thank you. This is strange. Because flashing only comes when the code for the remote is stored. I did an online search and found the receiver chip page www.sunrom.com/p/ev1527-rf-encoder-4-bits where you can see the datasheet. and in this page there is another example with Arduino www.dfrobot.com/blog-409.html But could not find solution for it. Perhas something is wrong with relay module.

Assalamu alaikum Muhammad, you can use any 12V power supply as this needs very little current like 200mA. so you can't find 200mA, you can use 500mA 1000A or any thing .

I believe I have left nothing without explaining. I don't remember anything about this module. to answer, it I would have to watch it. so you better watch and get answer. if you can't find the answer, it means this module can't do it. of course you can modify this module by soldering wires so when you presee ONE push button, turn ON two relays etc. Good luck.
