Send SMS/Text from Arduino using SIM800L | DigitSpace

Hello there, and welcome to another easy and step by step tutorial on how to send SMS/Text messages from Arduino via the SIM800L EVB version, on this tutorial we gonna see first how to send a simple text message and then how to send some data, and for example I took the DHT11... All you have to do is press the button :D.

This is the module that I unboxed on the previous tutorial:

Hello... All the Wirings/Libraries/Codes I've used are in the link below the video as usual, Don't forget to Subscribe ... some other videos about this module are coming.

Hello!! Great video.🙌
I'm using the same module (sim800l v2)
Can u pls tell me what you used to provide power supply? How much current and voltage rating should I provide for it to function properly?

Amazing video SurtrTech!....A quick question please, I am also using this sim800l evb v2 board also, but have no idea how to put it in sleep mode....Does anyone know how please?

Hello Yassine, first thanks for this Chanel. So i have bought Sim900 and sim 800 i have uses Maroc telecom card sim 4G+ the problem that shield didn't work. I have question which card sim have you used i saw this is NW but it s 4g too?

Don't you need a SIM card to connect to the cell service provider ? I look quickly on the website for documentation but couldn't find it.

3.7 lithimum battery and boost to 5V okay?


Also why don't you use vin to power the arduino from the battery? I thought the 5V pin was for output only

Great video, unfortunately I know the electronics well but not the programming as well although I slowly learn to learn. I have all the material at home and also the AM2301 module (DHT21), so I would like to do this project for 'with a diversity', remotely call, when I want, the system (ARDUINO + SIM + DHT21) without sending with the button. I hope I have explained myself. Can you help me?, thanks de IK1CFJ, Biagio.

Has anyone seen how to do this NOT using the SIM800L but with the newer Arduino Uno R4 WiFi unit?

WHAT IF YOU CONTINUOUSLY PRESS the button. Will it send many more texts??

[BenGuardian]

Aren't pins 1 and 0 tx and rx on arduino?

I tried to with4g giffgaff card in sim800L V1 but no luck
