Hello folks, I saw this L336 universal remote online with a learning feature. Essentially it allows to capture a signal from a remote and reproduce it. The interesting part is that it is able to do it without having a separate emitter and receiver. Here is a blog post of a teardown of this remote: https://goughlui.com/2020/10/11/review- ... ad-remote/

How does it capture the signal and then relay it back? I guess it is possible to read the signal from emitter and transmit it back somehow? Would love to hear everyone's thoughts on it.

Thanks for sharing.

It is most likely some dedicated internal circuitry of the main IC in the remote.

However, check out our blog post to see how it can be done using simple components.

They are probably doing something similar.
