Radio Control RF 433
October 1, 2020 - 3:18am

I'm trying to sort out a remote ON/OFF button for a LED. My solution was to buy a remote+receiver to complete this function.

I bought - VIPMOON® 14 Key RF Remote Controller, DC 5-24V Mini Wireless RF Remote Dream Color Controller for SMD 5050 2835 WS2811 WS2812B RGB LED Strip Lights(pic.1)

               - Ahevo G4 2835 SMD LED 350LM Light Crystal Bulb Lamps 4 Watt AC/DC 12V

            - 9V Battery

I have removed the connectors of the receiver. I have RED and BLACK at Supply(Battery) and RED, WHITE, GREEN for Receiver.

So i connect -  RED(Battery) with RED(Receiver) and Black(Battery) with Black(Receiver). SUPPLY

                     -  WHITE(LED) with GREEN(Receiver) and BLACK(LED) with RED(Receiver) LED-RECEIVER(pic.2)

Light is on at half intensity. ON/OFF button makes the light to change modes i belive because the light starts blinking in different mods after each press. Other butons  makes it blink(like is receiving signal but dosen't do what it sopposed to do). If i join WHITE(Receiver) with GREEN(Receiver) and WHITE(LED) the light intensity goes up and the buttons same things. I can't manage to turn it ON/OFF.

When i connect - RED(Battery) with RED(Receiver) and Black(Battery) with Black(Receiver). SUPPLY

                          - WHITE(LED) with WHITE(Receiver) and RED(Receiver) with Black(LED). LED-RECEIVER

Light is at high intensity. Whatever i press id dosen't do a thing. If i connect GREEN(Receiver) to RED or WHITE remains at the same intensiry and no response from buttons.

On the back of the Receiver RED is + ; WHITE between G G - ; GREEN D

 Can anyone tell me what i'm doing wrong? I just want to turn ON/OF the circuit.

Or can someone point me in the right direction to achive this simple function.(Like buying the boards-transmiter-receiver).

Thank you!

Try to connect the Red wire to +VCC the White wire to Ground and the remaining green wire goes to the Data Pin of the LED, if you are using a WS2812B LED Strip power them with +5V VCC more than +5.3V VCC and you have a dead WS2812b strip in your hand.

Debasish is right. The connection is written on the reciver. Two white wires as G (Ground), green as D (Data) and red as + (VCC).

I'm looking to achieve just ON/OFF function. That's why i was just tried to make it work on just that not for the rest of the functions. Anyway i have abandon that one and bought this new 4 channel receiver transmitter: https://www.aliexpress.com/item/4000589060257.html?spm=a2g0o.productlist...
 
So i have tried to follow the scheme and make connection like in the pictures. 
When i press the button it make the LED from the transmitter board to turn ON/OFF.
What i'm doing wrong?Thank you all for the answers and suggestions, much appreciated!rsz_img_20201002_081456.jpgrsz_img_20201002_081456.jpgrsz_img_20201002_083957.jpg

That is not going to work, because the receiver module is not designed to handle load current more than couple of mAps. you need to connect a MOSFET or a pass Transistor to turn on or off your load. Annotation 2020-08-18 082616.png

you can use the above circuit as a reference instead of the motor you can attach your load. the mosfet can be IRFZ44N, 55N60 or 45N60

Even if i don t understand complety the schematic it looks much better.

I have ordered some IRFZ44AN that will arrive tomorrow.

What i don t understand why i have 9V and 5V at he receiver? Is what is this.pngthat the IRFZ44AN?

Guess R1 has to be a resistent? What kind of?

Thanks again!

For resistive loads it is not required, but it is good to use a freewheeling diode in the above schematic. Who knows if problem happens.

the 5V and the 9V blocks represents the power supply. for your circuit you can directly connect 9 volts because your device supports it. and in teh schematic what you ask is the mosfet. try google searches for the pin diagram of a mosfet, you can understand it better

Everything look much clear now. Thank you for all the help guys!

I'll see what i can achive tomorrow and i'll return with the results.

 

Have a great Sunday!

Ok. I got the parcel earlyer then expected. With the IRFZ44AN i got some small 0.5A power switches. So this new ones have 6 pins(3 on each side) ..tried to replace my old 2A power switch and no more LED light on. I have wire it of 1 pin on each side. How should i do it?

Also i did some research on MOSFET and did the next scheme for my project.

Let me know how i did!

Thank you!

Ok. Back to drawing board. Something is not right ..i have searched on the web about wiring this kind of power switch and i found that middle pins should be connected with ground on the sides. Tried this why without having power to the transmitter. Changed it with the old one and the RED LED is on.

Trying to use the learning button on the reciver and no luck.

What i should do now?

Thank you!

Calibrate the both reciver and transmitter in same frequency. Maybe the reciver did not reciving signal. There is a potentiometer maybe.
