Muy ingenioso, requiere de filtros para limitar el ancho de banda porque las señales digitales tienen gran cantidad de armónicos que se incrementan con la frecuencia de los pulsos PWM. Felicitaciones

[@BabakStars]

I am glad that the video was useful for you. Yes, a filter is also used. But I think I found the main problem and I am working on it. By the way, the topic of the next video is the same.

Very good thank you!

[@BabakStars]

Glad it was helpful!

brother, can you make 4 channel transmitter or receiver by using RF 433 MHz module in an easy way and longer range plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

[@BabakStars]

Thanks for the comment. Yes, I think it can be done. But with my experience, it will work better on 315MHz frequency

[@EveryThing-db7gu]

ok brother make it with a 315 MHz module and also use a microcontroller IC or Arduino Nano for a quick response instead of an HT12 IC
also thanks for your help@@BabakStars
