✅SMS Messaging with Arduino and SIM800 Your Complete Guide
Today, we've finally reached one of the most interesting topics related to the GSM module SIM800. In this blog, we will write and test two programs. One is a simple verification program for sending text messages (SMS), and the other is a bit more complex, involving sending measured air temperature.
I've already talked about our module for connecting the Arduino Nano and SIM800 in previous videos. You can do without it, too. When working on this program, I used our developments from previous videos. The controller will send a command to send an SMS every time it's powered on or restarted.
