Arduino Sim800l Relay Control with SMS | Control Home Appliances with Arduino and Sim800l

This is a very simple project based on Arduino and SIM800L GSM module. You can control electrical home appliances by using SIM800L that is connected to a 2 channel relay module.
In this tutorial, you will be able to use the SIM800L GSM module for controlling anything through SMS. To do that, you just need to parse the incoming SMS from SIM800L extract message. After extracting the message Arduino will control your home appliances according to received SMS.
There are lot of GSM module available in the market but I personally recommends and prefers SIM800L due to its small size.

Woohh impressive sir. So cool. How I hope I could study deep the coding, kind'a hard for me to learn. I'll try harder to study this one. Thank you sir for making such innovative tech. ❣

Excuse me sir, everything works great but if I add a digitalRead in the void loop the messages dont arrive, like the communication is affected. How should I implement that without affecting the serial comunication?

[@shubhamubarhande2122]

Does this gsm module work on 4g sim?

[@rhingenieria6964]

the best video for sim 800l

[@ubaid7979]

Bhai is main pc add kar k rakhna pharega kiya programming upload kar k pc hata k power supply se used kar sakhte hai naa???? Number mil jaega to bohat help ho jaegi main bhi pakistan se hun

[@saitammali5138]

thanq so much broooo............!!!!! 100% working>>

[@moussaab8292]

Please, I have a GSM working on 4 volts, can it be connected to a 5-volt Arduino power supply and put a resistance to reduce the voltage

[@edgardoravier5641]

Hola, como estas. gracias por el proyecto y ponerlo a disposicion. Consulta cargue los codigos pero quedan las 2 digitales en on.

Hi sir, when we received reply message, need the date and time together with notification,

[@mustaphajammeh6723]

Hi,how can I integrate relay with the GSM module to send me messages.

[@moussaab8292]

I have a problem with programming, as soon as I write pine Mode( 7,OUTPUT) the relay works without defining HIGH in the program

[@user-ri8rs8xl9j]

you're the best!

[@kentbinaoro9164]

This is so cool.....I wish I could see your schematic diagram sir.. it is very hard to follow ... I hope you can help me sir for my studies.🥺

[@F3ChannelRs3]

Hi sir, is it possible to add more sender number? or remove that feature? cause i wanna register more than 5 numbers

[@mdsharifulislamsharif3545]

Hello,

[@chidiayoanasonye9243]

Can I power the arduino using same 5v adaptor ?

[@rajaduraisangari]

Dear sir, I have two questions 1)when gsm sim 800 power on, i need to received message, because here power cut 4 times per day,

[@ricardomontiel5198]

Hello sir. How can add an other phone for receive the message. I mean that two phones receive the status of relays

[@rajaduraisangari]

Dear sir, how to turn off the relay after 3 seconds automatically? Pls change the code for me thanks
