In this video I will show you how to control relay module with SIM800L DTMF commands using Arduino UNO. This is GSM based home automation project in which I will show you how to decode SIM800L DTMF commands using arduino then by using that DTMF Commands I will control the relay module. After watching this video you will be able to control relay and high voltage devices gsm phone call.

Warning: I will use High Voltages which if incorrectly or improperly used could result in serious injuries or death. So be careful of what you are doing because I will take no responsibility for any of your actions.
Warning: In some countries it is required to register gsm module from govt authorities before using it. So, get proper understanding of govt laws related to gsm technologies.
