Serial3 is not available on Arduino Uno,you can use Serial instead. You can follow two routes,the first ,use hardware serial,second use software serial. I prefer to leave hardware serial for debugging and software serial for pzem interfacing. Each two are easy to implement.

Oh thanks for the reply. Do you have some links to explain this to me? Thanx so much!

sergiocntr commented 4 years ago

You are welcome! That so easy....don't be scared ! Personal thoughts and sorry to say that there are tons of tutorial ,instruction , diy about that and this is not the right place where to ask this question. I know that first steps are hard but you have to do by yourself,I hope you understand. Look on youtube, instructables...You'll find what you are looking for and much more else!!!

I don't want a link with a code to copy and paste, I wanted a string to search on google! I wanted an explanation, not the code.

sergiocntr commented 4 years ago

"Software serial arduino uno" maybe? Have you tried? Is this so hard? Explain what? The hot water?

SimoneProvasio commented 4 years ago

I tried to search but it didn't specifically deal with the topic ... I'm sorry I'll try better
