One Channel Transmitter and Receiver with 433Mhz RF module

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

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

Querido amigo, en este video que muestras, ¿qué distancia máxima se puede alcanzar entre emisor y receptor? gracias

Just what I needed. Excellent, thank you

With these connections, is the receiver output suitable for driving a MOC3021? Thanks for your reply!

Can you tell me what the current consumption of receiver module when ideal ON but not receiving anything?

I have a problem. So, i built it but the receiver output is 4V. When I hold the button it drops to 1V for a second and then back to 4V. Any help?

Parabéns pelo vídeo amigo!!👏👏👏👏👍📡🛰️

whats the gain at the output can it gove rf burns ?

Can you please give the details on how to make the 2 antennas. Thanks.

These 433 mhz modules are great. I have been thinking and looking for several years for a 'scheme idea that would allow me to change music at some distance from my stereo. For example if I decide to put on a song, I would like to be able to change it using a tx and rx with a 'different music source. It is a small project of my interest. Can you experiment for me? Thank you very much.

what is the max. range of the distance ?

Can we use LORA modules in same way, without Arduino ?

What If i use two pair or more in home, work separately fine or is it possible to get mixed and interfere each other?

Hi good day… can I use this for tail light.?

What are you using to connect them

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?

Can I use lead acid battery instead of mobile battery

Kya led ki jagah moter chal Sakti hai

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?
