hi.
i read it and i know all of this.
i wanted to know what should i write as condition in if loop that says if it was "hi" then digitalWrite(13,HIGH);
please write an example for me...
Did you check the part that said:
along with the code explanation and comments? It should have made it clear how to do that.
I will explain to you how to write this code yourself, but I will not just write it for you. If I do that, you learn nothing about how the logic works.
what host microcontroller are you using and how is the SOM800l connected?
no it didnt.thank you
AT Mega 328 and its connected rx 3 and tx 2 via arduino uno
Which part did you not understand?
No voltage divider? That's not good for the SIM800l module, as you should have realized if you read the article posted above. Add a voltage divider, otherwise you risk frying your GSM module
