I'm trying to test the HC-12, i did some research but i can't get it to send and receive data.
The data is send from an arduino uno to an arduino nano. My goal is to push a button on the arduino uno and than then a led will blink on the arduino nano.
I Searched on the internet and I found this page and I tried these codes but it won't work.
that web page has too much fact and too little knowledge. note that none of the authors of the articles below has a problem with the HC-12 and software serial
