One Channel Transmitter and Receiver with 433Mhz RF module

[@emylrmm]

*important note* place a 100uF cap between VCC & GND close to the receiver. Any small ripple or noise or small abrupt changes in VCC will be amplified by the RX circuit and will show up as an output transition on the RX pin. This receiver has a lot of gain between VCC and DATA out, and that makes it very sensitive ( very twitchy ) to noise or tiny changes on VCC

[@astroalyn2010]

How do you determine what size cap tho?

[@emylrmm]

@@astroalyn2010 Noise immunity is the key. 100uF worked well for me, but 220u, or 330u or 470u would work well too. I suggest not going smaller.

[@FaizelMoosa-og3yl]

@@astroalyn2010 ask engineer

[@fridolineckerd6135]

I placed it between dat and gnd on the receiver side and it canceled out most of the noise i got.

[@slicybtw]

Mine keeps flashing and when i start transmitting it flashes slowly, is that noise or something else?

This was honestly the very simple answer I was looking for about these modules.

[@soumetrikya]

Very good video. it worked for me. Initially i used 9v. It did not work. Tried with 5v, it worked fine. Thank you. Just to get clarification. In this video, as per my understanding, the LED is always in ON state. Once the button is pressed, the LED turns OFF just for about few seconds and then back to ON state.. Can i have circuit having LED in OFF state initially and once the button switch is ON, the LED should turn ON. Later after the button left, the LED should OFF. Can this be implemented using single channel or should use HT12E and HT12D ic's?

[@ALEET]

probably switch the data wire to the other one

[@RND-USA]

Wait that’s crazy cool! So these modules have a built in signal? If so is it different in each module or is there a default code that they transmit?

[@pescandoideas]

When you connect it, the LED starts flashing. and when the button is optimal nothing happens. It seems like I have no communication. any tips you can give me

[@sumitranath2065]

Can I use lead acid battery instead of mobile battery

[@emylrmm]

yes, but put in a small fuse to protect the wiring. Many SLA batteries are capable of high short-circuit current

[@paneerpolice3454]

Will the transmitter work with other circuits?

[@HariKrishnanKodungallur]

Led keeps glowing all the time and when I press the switch the led gets dimmed for a second (not turning off). Even if I keep on pressing, it is not turning off.

[@avationawesome]

This is because the comparator cannot sink enough power to fully drain it .... try adding a stage of PNP BJT so that the LED Turns off properly

[@mattpi9153]

So what determines the signal? Will all transmitters shoot the same signal? Can we change that signal? Talk to me about the signal... :) Can we make one just as simple but more secure? This is very cool. But can you show us the next step UP? LIKE CLEARING SOME OF THE NOISE or adding range or another button. I've been using the arduinos but I'm not too good at coding. I can't seem to receive a signal and have that signal trigger an event. Not even to one pin
