- เผยแพร่เมื่อ 15 พ.ค. 2020
- This tutorial is about sending a SMS using a SIM800 GSM module with an Arduino. SIM800 module comes with different versions like SIM800L & SIM800C. You can use any of these and everything has explained in details in here. I hope to create more tutorials related to this and hope them in future.
Please comment all your doubts and unclear points in comment section and I will answer them personally.

Thank you for this video btw. You did really well.
Glad you enjoyed it!
Very Good Lesson. Thanks a lot
I've seen commonly using a diode to drop 5V to the required level. Btw - a nice video.
thank you brother ❤️
Hello, nice video. Is it possible to read senders number and replay to it with with some info. E.g. sensor value.. Thanks
Thanks for the tutorial! Unfortunatelly my SIM800c module is slightly different. It has the following sequence of pins:
Top side: 5v, V_TTL, GND, TXD, RXD, DTR, SPKP, SPKN
Bottom side: MICN, MICP, Ri, VRTC, GND, PWR, GND, VBAT
The vendor told me that the module already comes with an internal antena, but it also has a connector for another external one. So I decided do not purchase the extra antena, and now I wondering if this can affect the behaviour of SIM800c.
The module is being powered from an external 12V power supply connected to a step down module lm2596 adjusted to give the 4V required by SIM800c. I also use the capacitors and the zener diode as recommended in the module datasheet. The power supply is connected to the 5V pin, and when I turn on the circuit a red LED light up indicating tht the the power is on, but no blinking LED appears on the module.
Before trying things that can damage my module, I would be very happy if you could help me to answer the following questions:
Can I power the module with 5v through the 5v pin, instead of 4v? I want to trying this because I’m getting around 2,74 in the VBAT pin, when I power the module with 4v. I also ask to myself why there is a 5v pin in the module since the maximum voltage recomended for SIM800c is 4.4v.
Can I power the module through the VBAT pin, using the same power supply or a 9v Ni-Mg battery + step down, instead of the Li battery recommended in the datasheet?
Should I use an external antena as well?
Thanks in advance.
My module is the same showed in the link www.bizkit.ru/en/2019/02/05/13553/
you cant power from 5v pin.
And also it requires atleaset 2A current from the supply
Amazing video
Good video. This is good to learn, or made projects for your house. I See you video Facebook Group, I subscribe you Channel :).
Thank you very much brother
Very important video💪
Glad you liked it
I am using a pic microcontroller to do the same thing. I receive the message but my phone says content not supported.
Is it possible to power the Arduino from the same power source such as the lipo you are using ? In case some switches are added to the project and an lcd screen as well, it could make a nice portable phone.
Arduino will need 5v to work. This lithium battery will only provide 3.7volts. So you may need to use a dc boost converter to boost 3.7v to 5v in order to power arduino. This will work fine and i have used that method without any issues. Please try my other videos also to get new ideas
how much current does the connected cell provides?
is it able to compensate for the 2A requirement at transmission burst?
Yes. This battery is capable of supplying 2A when needed
Nice content Gr8
Great video
wooooooow. great....
Thank u
Hey bro,
I am going to have a SIM800C shield which is my own. I want to ask something; which pins are correspond to RX and TX in SIM800C? Are they UART1?
Sorry for my ignorance.
Can you show me the module. Same chip is used in video
may i know why have you connected the reset pin with ground pin?
Coz its sim800 C module
Bina capacitor use kiye kar sakte hai?
Hi...Is Arduino output pins(Tx,Rx) voltage level (5V) compatible with SIM800 pins voltage level (which may be 3.3V) ?
Yes. It is compatible. No need of logic level converters
What are the total costs of all modules used in this video?
can you use 4g on the gsm800l
Hi, thanks for this video quite useful, I was wondering, do I have to connect the rx if I am planning only to send sms ?
Yes you should
@@tronicslk How come? There must be a reason.
Hey bro mu gsm is not working at commands are not showing please any solutions?
when i connect 3 grounds together the sketch is not uploading , and when i remove the ground from srduino the code runs but no response from the sim800c?
Need to see circuit and check the components. May be GSM module is burnt
power supply is not correct that's why it off the arduino after removal it starts to blink the arduino
Ciao. Molto interessante e utile. Ti chiedo gentilmente di dirmi se è indifferente usare anzichè ARDUINO UNO il mod. ARDUINO NANO penso sia possibile; cambiano i cablaggi? Grazie e saluti
È lo stesso amico mio
Is it compulsory to use only 2g sim with 800l or i can use my airtel 4g sim with this
You can use any sim
Sir, I am also your subscriber. Answer me as well.
I asked you sir that GSM module is not messaging on Android phone. Please answer this.
there are lots of reasons which cause this. cant tell exactly without observing
@@tronicslk Sir call is doing GSM modem but SMS is sent. Sim shows in memory but does not show in phone.
the status led does not blink at all on my SIM800C , What is the problem?
may be damaged module or wrong power supply
Super
Sir, this module is not messaging Android phones. It is a small multimedia phone, messaging it.
Please reply me
should observe the circuit
if the module's led is not on does it means the module has problem?
Yes. If u provide power properly, there is a issue with module
Hi can i send same Msg to Multiple Mobile numbers (eg- two mobiles) if yes can you tell me how to edit code?
Yes
@@tronicslk can you tell me how? Would be a huge help 🤗

Aurdino me Jo library Jo use ke hai apne uski zip file dedo
nice..
💥💥✌️
Code file is not open sir
Ayye mekama temperature eka menala eka ganakata wada wedi wena kota alert message ekak ganne kohomada

What is a boot pin used for ?
i have explained it
I think that u may put the name of the component in the video
Sim800 + 2200uf capacitor. Thats all
Is it necessary that we should use 2g sim card. I have no 2g sim card and i can't find it anywhere
Dada please tell me i am in trouble pls help me 🙏🙏🙏🙏🙏
Vodafone Airtel will work not jio
Sir where we can find software serial Library? pls help sir
it comes with arduino ide by default. No need to install again
super
Thank you
what is the size of the capacitor?
u can see it on video. 1000 uf or 2200uf is good
Place a call ! 😂👍
sim800l eke power consumption kohomada
Stand by 18 mA
Call
GSM850 199 mA

can i use 4G sim for sim800L
Yes you can.
Why you use capacitor
To Stabilize the voltage
Do this work the version 2 of sim800?
yes. It will work
What parts of the code are needed to be changed if ak
Sir we r tried so many times but it's not working sir... Plz give some solution
watch the video carefully
I Will use 3.3v then
not enough voltage and current. Dont use it
Sor I am not receiving message sent...
Is GSM module working properly (power supply and led blink rate)
SIM is 2G,3G or 4G ?
yes you can use all 2G,3G,4G,
but server internet output 2G
Rohith is correct
Sir can you re send this code
it is in description
I have a module
sim800l v2
and its not working
Did u give power correctly?
And how to power it corectly...
This is fake.
Reason?
In receive SMS mode. I able to get the message send from mobile phone.
But it include some other text
for example if I send "Hello", in Serial Monitor I'll receive ⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮ .. (and other information) Hello.
Is that normal?
How to get retrieve only "Hello" I don't need other information.
I have done a seperate tutorial on this. Please watch it ✌️
@@tronicslk Thank you
