✅Arduino SIM800 connection and test #01
Arduino SIM800 connection and test. This is an introductory video in which I will talk about the nuances of connecting the most affordable Arduino Nano controller in every sense to the SIM800L GSM modem.
And I will also show the simplest manual way to check the connection between them.
Since we decided to discuss the SIM800L and the Arduino Nano controller, we must keep in mind that the GSM module has a recommended supply voltage of 4.2V.
