You can easily use an old phone to do this as well since virtually all mobile phones since the beginning has an exposed AT interface via the modem and you just connect with a serial interface just like the example here in the video. I have reused many old mobile phones as remote alarm senders in the field. I charge the phones with solar cells and they run forever unless something goes wrong... I do all of this with an atmega328 - which runs from the phone battery as well - and if the battery stops charging it sends an SMS when it falls below 10% so I can go out and swap the phone. Very cheap and useful usage for old phones!
I can't believe I didnt hear of you until now. I guess I was busier in the past few years. You have inspired me to take my hobby to the next level, thank you very much, I LOVE YOUR WORK!!!!
Hey Scott, I love your videos! I'm just a beginner in electronics world and still only blinking LEDs and stuff like that, but I had an idea of using smartphone as accelerometer/gyroscope alarm for my motorcycle, but most android phones do not want to do anything while screen is off, so, are unusable... But this seems like it could be a way to go, could it be used on battery thats charged by generator and have some movement detectors? My idea is to send sms or call if bike is moved, maybe even do some feedback for the one moving it.
please help, the gsm module sends a message to the phone,,but how can you send a message back to gsm module?,,,example i will text "UNLOCK" to the gsm module then a pin will be high and a door will unlock.
Hallo Scott, ich weiß das Video ist schon etwas älter aber ich benötoge gerade das SMS modul für ein Projekt. Nur leider funktiert es nicht im Seriellen Monitor bekomm ich nur: Write your SMS: Send SMS..... Sucess funktioniert das board auch mit 9 Volt oder benötige ich umbedingt 12 Volt ? ( IC Entfernt) Dave
Do developers typically write software on top of AT Commands (i.e., they create libraries that ultimately sends AT commands to the M95 chip to get it to do things like send SMS (and other features of the module))?
One would think they switched it on the labelling for Tx/Rx so you didn't switch them up accidentally, so any beginner that didn't know that you had to insert them backwards would get it right first time.
Can I use any of gsm shield model to connect to Arduino Uno? I'm doing home security with sms alert for my university physics project. Is it going to be any error if I use any of GSM module? I prefer cheaper ones that work fine
I have something like this only using a small PICAXE micro attached to the "AC fail" line on a UPS, it sends me a message when the AC line flickers a bit, completely fails and when it comes back on
So I have a 12V 1A adapter, and I removed the maxim thingy from the GSM module. But when I plugged the power source in, the thing started to fizz and I saw smoke coming out. So why do you say that it can handle 12 volts?
+joster222 Okay I DIY'd an adapter of 4.5V and 500mA. No more sizzling or smoke. But now I have a different problem. I inserted the Simcard, but now it justs blinks a few times and then stops. Does that mean it can't connect? I made sure that the simcard is correctly inserted.
its my understanding that "GSM" is no longer working! the phone system has changed and i dont think your device will work? they have gone to "LTE" is this correct? and is this video obsolete?
It depends on your mobile operator. Some operators have stopped supporting GSM/2G and therefore require a 3G/LTE compatible module. Even when it is something as simple as sending a SMS. Other operators still support GSM/2G. You have to ask the mobile operator what they support.
Hi!I think this is the perfect Project to get my home alarm to send an intruder alarm via GSM/SMS. But I'm a little confused how the Arduino is trigged at an alarm ...The switch at the GSM board is just to get the board ready=establish connection with the GSM Net. Right?or...Will the predefined SMS message be sent when switch at the GSM board is pressed?or ..Should some pin at the Arduino be activated in order to send a SMS? If yes, then the sketch for Arduino would be rewritten?Nice if you will sort this out, because I want to send a SMS when my home alarm is activated!Regards misterleffe
Can you use this same principle to send Cellular data? Im designing a tablet on my own to really push my knowledge. No im not gonna sell it or release plans because its just for me and im not sure how well other people would like my first design lol. Im trying to make a portable retro gaming tablet. STOP. YES I CAN BUY ONE. I DONT WANT TO. I WANT TO BUILD ONE.
My led diod is blinking every 1 sec. (not 3sec) . I dont know where is the problem i tried 2 SIM cards from different operators and it still doesnt work. Can you help me please ? I will be very happy
hi..im am currently working on a project which is gsm LED notice board.i am using the max7219 8x8 led matrix...the gsm sending and receiving part had already done..now im having problem to display the message from the gsm to the LED matrix..can somebody help me pls ..i have only 1 more months to present the project.. :(
Hallo, vielen Dank für das starke Video, ich würde auch gerne SMS mit dem TC35 verschicken, mein Problem ist, aber,dass es sich nicht verbindet. Ich habe den Code auf meiner Prepaid SIM entfernt, aber nachdem ich auf Verbinden drücke blinkt die Lampe ohne Ergebnis, habe es an mehreren Orten versucht und auch mit verschiedenen Stromversorgungen, ich weiß momentan echt nicht weiter Hilfe wäre nett, danke
GSM is changing. 3g is being phased out world wide. Unless your module is 4g capable it may stop working. To find out when, check your mobile service provider!
well the last time i checked Arduino can do only simple or/and/if commands and can only process up to 8 bits of data or higher depends on your chip,but a modern day phone has a CPU in it which can process farrrrrr more data than a simple chip
BeGamerSl well, other processors can work with 32 or 64 bits but they still do the same operations, the only limit of the chip that arduino uses is the flash storage size
Guys i need help, my module can't connect to the network...The led just keeps blinking...i connected everything fine i don't know why it's doing that can anyone help?

Jens Andree Awesome!
+Jens Andree .....do the phones have to have an active service?
+Luis Gonzalez Yes. Use the cheapest pre-paid card you can find and you're done!
+Jens Andree Can I have ur email? I think I need to discuss something with you. Thank you
Thank you Jens. I have read your email and I could get your points.
I can't believe I didnt hear of you until now. I guess I was busier in the past few years. You have inspired me to take my hobby to the next level, thank you very much, I LOVE YOUR WORK!!!!
ich finde es gut das du auch "kleiner" tutorials machst über solche sachen. Da kann man als anfänger gut sich sachen abschauen!
weiter so!
Hi GreatScott! I've been watching your channel for a while now, and just want to say I love your videos! Keep up the great work!
Going through all your videos. Your channel has exploded sir! Thank you for all your hard work.
LOL When he pressed the button at 2:16, a FaceBook notification came up at the right moment.

I appreciate your helping us to send SMS, can you provide me the code for receiving sms?
please help, the gsm module sends a message to the phone,,but how can you send a message back to gsm module?,,,example i will text "UNLOCK" to the gsm module then a pin will be high and a door will unlock.
GreatScott! can we send a image with Arduino or some other processors??
Thanks a lot, I always wondered how to do this. Can't wait for the follow-up.
"Electronics Basics"
was just thinking this lol
and as always great videos from GreatScott!
Thanks ;-)
The new intro is NICE!:D
you ar the best +GreatScott!
Excellent video! But I have a question. Why in a part of code says "if (text[i - 1] == 46)" ?. Why 46? What does it mean?
46 is the ASCII code for a dot ('.'), its probably the code that sends a SMS at the end of a sentence.
Thank you very much! :DD
What a cool use for an Arduino!
Love how you say siemens as Ziemens.
Ramses De Vuyst It's German company, GreatScott is from Germany... so i think he says it correct ;)
Excellent video! Very informative with great detail.
Very good and funny videos bring a great sense of entertainment!
Hello bro,
why don't you make a video on the cheap gsm module SW M590E/NEOWAY M590.Which is much less cost then other .it is less than $12
Hi. Sending SMS can lock or unlock your door security?? Or it just send a notification alert when there is an attempt of an unknown person.???
Can i send SMS for more number phone ? Can i control send SMS in C# application ?
Hallo Scott, ich weiß das Video ist schon etwas älter aber ich benötoge gerade das SMS modul für ein Projekt.
Nur leider funktiert es nicht im Seriellen Monitor bekomm ich nur:
Write your SMS:
Send SMS.....
Sucess
funktioniert das board auch mit 9 Volt oder benötige ich umbedingt 12 Volt ? ( IC Entfernt)
Dave
hey can you explain a little on the use of other pins?
I am unable to download your code from the website Instructables, what i suppose to do?
hi, I think you are a great Electronic Engineer.........do you have a " RAPSBERRY SECURITY CAM" VIDEO???
You mention about alarm system. can you make power failure alarm system using this one? that would be nice. Tnx
I want a friend like Scott!
Do developers typically write software on top of AT Commands (i.e., they create libraries that ultimately sends AT commands to the M95 chip to get it to do things like send SMS (and other features of the module))?
GreatScott can u please write the code for sending an SMS with a phone to the GSM to switch ON three LEDs
john assuah No time
Thanks man! Habe so lange auf das Video gewartet. Would there be an easy solution for the RPi as well? Cheers!
SvizzTech
Du kannst das Modul über die RS232 Schnittstelle deines PIs steuern, du kennst sogar die Befehle für das Modul.
Und sogar die Baudrate!
One would think they switched it on the labelling for Tx/Rx so you didn't switch them up accidentally, so any beginner that didn't know that you had to insert them backwards would get it right first time.
You make it seem easy!
Wow this seems too simple to be true!! Do you have to download a library to Arduino? (I can't find one online)
It works without any additional libraries.
Oh ok thanks
Have you already uploaded the one where you make this system into a security system? I would love to see that one!
SicherNygren I will upload it in a couple of weeks.
Tolles Ding! muss ich mal ausprobieren!
Can I use any of gsm shield model to connect to Arduino Uno? I'm doing home security with sms alert for my university physics project. Is it going to be any error if I use any of GSM module? I prefer cheaper ones that work fine
Can the opposite happen? For example you send a message and arduino makes a task for you?
KOTSOS5 Yes, that works as well.
GreatScott!
Wonderful then! I hope you show that us too, it would be perfect for an irrigation system!
Wait a second... Why would you solder that jumper on the button when you could have just connected it to the appropriate pin?
I have something like this only using a small PICAXE micro attached to the "AC fail" line on a UPS, it sends me a message when the AC line flickers a bit, completely fails and when it comes back on
Good work :D - I'm assuming this device can receive SMS with little effort, am I correct?
Christopher Liggins Yes. I am not sure about the little effort though.
hello scott! i am from canada will this work in canada with bell 4g network? thanks
Can you please make a video on how to use ths GSM module with 8bit atmel microcontroller/Arduino?
Thanks in advance
liked and subscribed
When I powered the GSM module and Arduino, the code didn't work. Could you explain what's the problem?
I have a GSM module. But i can't able to use it successfully. Can you help me?
If you use a prepaid sim, can it send a message without a prepaid credit or load?
Is it possible that the arduino can send sms back to the incoming number which does not have been set in the code?
Can u help how to use old mobile as a gsm module for arudino..
Coz it Involves many connections
Could you do a video with the FONA module too? :)
awesomefacepalm No. Adafruit has a tutorial about it.
So I have a 12V 1A adapter, and I removed the maxim thingy from the GSM module. But when I plugged the power source in, the thing started to fizz and I saw smoke coming out. So why do you say that it can handle 12 volts?

Other operators still support GSM/2G.
You have to ask the mobile operator what they support.
Do you need to power it allways from a 5V power supply? Can't you just power it from the arduino itself?
The module can draw up to 1A peak while sending a SMS. Your Arduino will not like that.
GreatScott!
This module is a bit more powerfull than the others I've seen o.O
But it's possible to power the arduino throw this module?
No, the module uses 3.3V power. Arduino needs 5V.
GreatScott! You could use a 3.3v arduino though right? Maybe a nice cheap arduino pro mini clone off ebay?
Hi,
ist es denn schwierig, das gleiche mit einem Raspberry pi 2 zu realisieren,
oder könntest du das evtl sogar mal zeigen?
Can sim900 module do all the same things as your TC35module can??
That's so cool! Thank you!

get a magnet switch connected to the Arduino write a sketch that will send a message when the switch is deactivated
I didn't understand the line "mySerial.println((char)26);" what this 26 means?, i tought that is the lenght, but the message only have 21 characteres.
Marcone Filho : it means control+z, it tells the modem to send the message
can u use any number you like or just the number of the sim card?
The number of the sim card
GreatScott! okay thanks. love your vids!
Can you use this same principle to send Cellular data? Im designing a tablet on my own to really push my knowledge. No im not gonna sell it or release plans because its just for me and im not sure how well other people would like my first design lol. Im trying to make a portable retro gaming tablet.
STOP. YES I CAN BUY ONE. I DONT WANT TO. I WANT TO BUILD ONE.
My led diod is blinking every 1 sec. (not 3sec) . I dont know where is the
problem i tried 2 SIM cards from different operators and it still doesnt
work. Can you help me please ? I will be very happy
Is it possible to make multiple calls using arduino?
Good programm, but i would like to put in the sketch, a only number cellular autorized, and so with others numbers nothins happens, help me!
What card is it ? Where can i buy a pre-paid sim card ? Does it have any other names ? I dont know any kinda card here.
Just wander into a supermarket and ask if they have SIM cards. They usually do. If not, go into a phone shop and ask them for one.
Yeah but they offer subscription, and thats what i dont want to
I'm sure you'll be able to find one that's pay-as-you-go

hi..im am currently working on a project which is gsm LED notice board.i am using the max7219 8x8 led matrix...the gsm sending and receiving part had already done..now im having problem to display the message from the gsm to the LED matrix..can somebody help me pls ..i have only 1 more months to present the project.. :(
And the people can chat free without Wi-Fi or Cellular ?
Greatscott do you have an email that I can contact you with because I would like to share some ideas with you and want some help on them. Thanks Bob.
Bob Bennem You can contact me over facebook and twitter. But I usually do not have the time to help others with their projects.
can i use a modeme DSL in place of GSM module ?
Mine doesn't connect to the mobile network it doesn't even blink when i click the btn? is my board broken?
will this gsm module and your code work in india?? pls reply
😂😢😑
Awesome video
Please help me with the sketch... m using sim 900a and am unable to send or receive the messages via arduino
please help
I have not found Arduino projects, send text messages via smartphone using bluetooh.
thanks

Anyone know what type of FTDI breakout was used. I know that it is 5V rated
Sir please make a vidio for WIRELESS UPLOADING PROGRAM BY ANDROID PHONE USING THE BLOOTOOH hc05 to AUDRINO UNO.
Next video on this topic please
GSM is changing. 3g is being phased out world wide. Unless your module is 4g capable it may stop working. To find out when, check your mobile service provider!
sir what is the code of that program?
you can use this device for making smart home products
How to send messages to multiple numbers?
nikolai wm : you simply write a code that will send sms to all numbers stored either on simcard or the modem itself
Can i send image from arduino thru sms?
Can you create a machine that can send free SMS ?
hola espero me pueda ayudar
tengo una tarea en la cual tengo que enviar un sms desde arduino pero con mi ubicacion
4:43 i see you were doing it before :))
testing it i meant
what is the use of ftdi? noob here
Does it support 3G or LTE
ardu ino : kindly go through the datasheet, you may get answers.
Omg i would love if you show how to make an arduino phone !
Lieberdk you can't
BeGamerSl tell me why, the only problem would be the size
well the last time i checked Arduino can do only simple or/and/if commands and can only process up to 8 bits of data or higher depends on your chip,but a modern day phone has a CPU in it which can process farrrrrr more data than a simple chip
BeGamerSl well, other processors can work with 32 or 64 bits but they still do the same operations, the only limit of the chip that arduino uses is the flash storage size
Don't wireless handsets have those simple processors inside.
ARDUINo UNO ARDUINO UNO, thats what i heard so far with these Elecronic Basics
what happens if you forget the dot?
BeGamerSl defcon15
does this work with a 3g sim?
Took me so long to realize my boards rx and tx were mislabeled, and its a completely different board
Where are you from?
Du lebst in Deutschland?
Guys i need help, my module can't connect to the network...The led just keeps blinking...i connected everything fine i don't know why it's doing that can anyone help?
Please make a new video on this topic with sending whatsapp message,
GreatScott! hab dich beim Whats app dass vidio war spannend
Please, can you give me a GSM module. I am going to make project for nexplorer company, but I don't have money. Please can you give me.
New intro!
Do you have a Xiaomi phone? :D
He has a Samsung phone
