As it is hard to describe, I made a small video showing my issue: https://vimeo.com/521857517
As you will see, the RF transmitter and receiver are correctly connected as they work when I touch a specific part on the transmitter. If anyone could help me understand what is wrong (and how to fix it), I would really appreciate it.
I also tried connecting a 100K resistor to it (with electric tape for now) and to ground and it works as well...
I’m using a 1M resitor on the encoder and a 470K on the decoder... could it be the problem? Thanks
