SIM800L Blynk | How to Control Relay with Sim800L and Blynk App

SIM800L Blynk is a video tutorial in which I will show you how to control relay module, with sim800l and Blynk App and Arduino, from anywhere in the world. This is a home automation tutorial and I am using gsm module to connect to the blynk server and control two 220v ac light bulbs. I am using Arduino UNO instead of NodeMCU (ESP8266). You can also use sim900 gsm module instead of sim800l with a little bit of change in the project.

In this IOT home automation video I am using following components
5 - Blynk App
6 - Blynk Library
7 - Tiny GSM Library
8 - A Sim Card

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.
