Why do you use arduino pin 2 and 3 as RX and TX . Thought arduino uno RX and TX pin are pin 0 and pin 1. Please explain to guide me

I want serial communication to computer. and usb uart pin0 and pin1 are used for usb serial. and these pins are also used for uploading code to arduino. and we cannot use these pins to communicate both with sim800l and computer at the same time. that's why I did not use them. So, I have used pin2 and 3 to communication with sim800l using SoftwareSerial library. you might use pin0 and pin1 to communicate with sim800l.

The problem is that I can't change the state of the relay. Theoretically, when I press on a switch on my phone, the relay should be open/closed. Instead, nothing happens. I've checked the pins connected to the relay; they are powering on/off, so I doubt that it is a coding issue. But nothing is there in coding part or connection. So how to resolve ta issue. Please help

Dear Ahmad, It was a very nice video. Thank you for that. If we want to connect an LCD (2x16) to the circuit, how do we need to revise the code. Can you please help

then lot of changes are required. make a function for your lcd. then use that function to display required data to the lcd
