Yah but I agree.

Thanks for all your awnser, after studying a little bit into the RF module I found out my problem, the left side of both encoder and decoder are the Address PIN, which means they will only communicate if those addresses are the same, that was what I was making wrong, I left them all at 1 and changed the resistors ht12ee them both cause the TX need to have 20 times the resistence of the receiver, in other words 50k and 1M resistors.

Be the first to write a review. I’m ht122d on a similar circuit.
