Sending text messages from your Arduino can be a bit of a hassle. In this tutorial, I’ll show you a

simple way to send text messages with your Arduino for around $20.

If you want to send a text message from your Arduino, you’ve got basically three options:

Use a GSM shield

Use an ethernet shield to send emails to a wireless carrier’s email-to-SMS gateway

Plug your Arduino into a computer via USB and have a script running on your computer that

uses the aforementioned email-to-SMS gateway method.

Unfortunately, these methods are either expensive, require somewhat complicated code

(depending on your coding abilities), or both. The last two options also require you to be within

range of an internet connection or a computer, which isn’t always possible.

Fortunately, there is another option that is cheap, requires only basic code, and allows you to use

it anywhere you’ve got power and cell service: use your Arduino to interface with a cell phone

over a serial connection. In this tutorial we’ll be using the Motorola c168i, which can be found on

Craigslist or eBay for less than $20. You may also be able to use Motorola’s C257, C261, V175,

V176, V177, C168, W220, and W375, as they share the same serial co nnector. You might be able

to use another kind of phone provided it has a serial connection (very uncommon in newer

phones), but it will likely have different serial pinouts and / or a different set of supported

commands.

10K ohm resistor

Pushbutton

Steps

1. Set up your C168i.

You’ll need to make sure th at your Motorola C168i is w orking properly and that you can

send text messages from it. If you browse the phone’s settings, you can choose to do a

master reset as well as initial phone setup.

Set up your C168i according to your carrier’s settings, and ensure you can send a text

message from the phone itself before continuing.

2. Solder wires to your connector.

You’ll want to solder o ne wire to each of the three co nnectors on your 3/32 headset

plug. The tip connector will be our serial TX connection, the ring connector will be our

serial RX connection, and the sleeve connector is our ground connection. In this photo,

my blue wire is TX, white-blue wire is RX, and green is ground. Use a multimeter to figure

out which pin connects to which part of the connector if you’re not sure.

3. Make the connections.

Connect the TX to pin 2 of your Arduino, connect the RX to pin 3, and connect the ground

connection to GND. Connect your pushbutton to pin 8. Make sure to use the pull down

resistor, or you may get false readings. See the image below for a wiring diagram.


4/21



4. Modify & upload the code.

Substitute the phone number for your own in the example code (found at the bottom of

this post) and upload it to your Arduino.

5. Plug it in and test it out.

Plug the 3/32″ headset plug into the headphone jack on the top of the phone and push

your button. The on-board LED (13) should blink when the message has been sent. You

can verify this by going into the phone’s outbox. If the message doesn’t send, or themessage doesn’t appear in the phone’s outbox, double check your wiring and ensure there

are no broken or shorted out connections, especially in your headset plug. You can also try

unplugging and re-plugging the headset plug.

Demonstration

Send SMS from Arduino using Motorola C168i

Example Code

The example code is fairly basic. It uses the SoftSerial library (included with the Arduino IDE) to

set up a software serial connection on any pins that we want. Once we establish the serial

connection, we use AT c ommands to wake the phone up, enter text mode (as opposed to data

mode), create a new text message, and then send it to the appropriate phone number. We then

wait 10 seconds, giving the phone enough time to send the message, and then delete the

message from the phone’s outbox.

I believe it’s possible, but I haven’t looked into it yet. It appears, according to page 3-70 of

this document that there is an AT command that’ll let you read messages. I know that Matt

Sheffield was working on that functionality, so maybe give him a shout? If you figure it out,

I’d love to see the results.

This is pretty awesome. Do you know if the phone can send SMS back to the Arduino over

Serial? That way you could interact with the Arduino over SMS?

Mike Septemb er 21, 2012 at 1:17 am

Jeff Murchison September 21, 2012 at 9:54 am

As far as I know, you can’t duplic ate a SIM card. A SIM card can only be registered on a

network once, and that’s to keep people from duplicating their cards and sharing them with

their friends so they don’t have to get their own service.

If you can’t use your existing SIM card, then yes, you’ll have to get a new one. Your options

entirely depend on your carrier. Personally, I use a pay-as-you-go account, which cost me

$10 for the SIM card. Some carriers give them away for free. You might also see if you can

set it up as a family plan or something, where the cheap new phone draws from your

existing text message package. The $20 was a startup materials cost. It’s impossible to

predict how much it’ll actually cost everyone, there are too many variables; location,

carriers, carrier rates, how many messages people will send, how long they’ll keep it going,

etc.

So, in practical terms, you have an Arduino watching something- maybe a sensor on a garage

door so you know when your spouse comes home- something. The event happens and the

Arduino texts you that it has.

That part I get. The phone part I do not. Warning! Stupid questions follow!

“A wo rking SIM c ard”. There is one in my p hone- but that is t he p hone I want to receive the

text on. Do I have to have service for two lines? Can I duplicate the SIM in my current phone,

put the duplicate into my e-Bay cheapie and more or less text myself? I’m not clear how the

phone end of it works in a day to day sense. Additional service sorts of busts your $20.

by way of example, you can get a pay-as-you-go phone at W*lmart for about $15.

Veriz*n h as a pay-as-you-go plan that runs $3 0/month, but you can pre-pay $ 100 and

you are good for a year, or until you use up all your credit. Typically, accessing the

network costs $2 each day and calls and text messages are some nominal amount

comparable to other plans. So, for example, if you set up the Arduino to send a text

message only every 3 or 4 days with the tempreature in your cabin, or if it dropped

below 40 degrees F, you could monitor the cabin for about half a year, so about

$16/month. I think there are strictly SMS plans that might cheaper.

Hari Marc h 15, 2013 at 12:42 am

Hi

Thanks for this wonderful page. I am building a SMS based temperature alert system based on

this page.

Excuse my poor knowledge in embedded programming, but I have a doubt.

The temperature sensor is an analog input right?

So how do we replace the “if (digitalRead(8) == HIGH)” expression so that it will serve my

purpose.

I want an alert SMS to be sent when temperature crosses 25 degree celsius which corresponds

to 250mV output from the sensor.

Do we need to initialize the pin as analog?

Thanks in advance.


9/21



Jeff Murchison Marc h 15, 2013 at 12:47 am

Use the AnalogRead(pin) command.

http://arduino.cc/en/Tutorial/AnalogInput


Thanks Jeff!

Now that I came to know about the examples page of arduino website, I think I can tackle

almost any problem I get on my way. Appreciate the help.



According to goog le, they are identic al, so it should work.

By the way, the phone I acquired for this project is Motorola C168, not C168i.

It will still work, right?


I used the following code:

#include

SoftwareSerial mySerial(3, 2); // RX, TX pins

void setup() {

pinMode(13, OUTPUT); // Initialize pin 13 as digital out (LED)

pinMode(8, INPUT); // Our button pin

mySerial.begin(4800); // Open serial connection at baud rate of 4800

}

void loop(){

if (digitalRead(8) == HIGH){ // On button press

digitalWrite(13, HIGH); // Turn LED on.

http://arduino.cc/en/Tutorial/AnalogInput


10/21




Check out step 5 above.

It also appears that the Include line is missing the SoftwareSerial. It should be:

“#includ e < SoftwareSerial.h > ” (remove the spaces b etween the < and > )

mySerial.println(“AT”); // Sends AT command to wake up cell phone

delay(500);

mySerial.println(“AT+CMGF=1″); // Puts phone into SMS mode

delay(1000); // Wait a second

mySerial.println(“AT+CMGW=\”+1919447786559\””); // YOUR NUMBER HERE; Creates new

message to number

delay(1000);

mySerial.print(“Sent from Arduino.”); // Message contents

delay(1000);

mySerial.write(byte(26)); // (signals end of message)delay(1000);

mySerial.println(“AT+CMSS=1″); // Sends message at index of 1

digitalWrite(13, LOW); // Turn LED off

delay(250);

digitalWrite(13, HIGH); // Turn LED on.

delay(10000); // Give the phone time to send the SMS

mySerial.println(“AT+CMGD=1″); // Deletes message at index of 1

digitalWrite(13, LOW); // Turn LED off.

delay(250);

}

}

Although I c an see the LED blink, No SMS was sent. I am powering the board using usb from

computer.

Is that the problem?

There was also one more difference in what I did. I did not use a resistor, I just connected pin 8

to 5V of the arduino for a second directly.

What do you think the problem is?

Taalouch Fradj Marc h 19, 2013 at 8:03 am

if I want to do a simulation, what software can I use?

Karmel Marc h 29, 2013 at 4:05 pm

Hy , you can just useISIS ,however configuration it self is not as simple as that

thank you

Jeff Murchison Marc h 31, 2013 at 11:58 pm

Depends if the Nokia has a straight serial connection available, and if it accepts AT

commands.

i want to ask..if i use nokia 3310…i can use the same code as above?

Marc Apr il 4, 2013 at 6:36 pm

Jeff Murchison Apr il 24, 2013 at 8:49 am

Make sure you have your set to the correct baud rate. Other than that, I don’t know what to

tell you other than make sure all the connections are correct.

Hi Jeff,

I copied your sketch on my arduino uno and connected a Motorola C261 as you descibed.Besides some beeps it produces nothing.

I also tried to read out any data from the software serial, without any success.

Any Ideas?

helmi Apr il 24, 2013 at 4:42 am

Jeff Murchison Apr il 24, 2013 at 8:48 am

Some people have gotten other phones to work, yes, but you’ll have to do a bit of research.

can i use anothor phone (samsung, nokia) to replace motorola 168i ?

thank you.

SMS for my thesis. Can’t wait to try this out

I’m pretty sure that there should be a 3.3V levels at data lines. USB data lines operates at3.3V as C24 module inside the phone does.

Nice article BTW.

Thanks for that idea.

Nope.

is this not require rs232 to ttl converterl like MAX232?

Janni May 21, 2013 at 8:19 am


Did you try the last line of part 5? (“You can also try unplugging and re-plugging the

headset plug.”)

Hello Jeff,

thanks for this nice post. I just copied your example code and used it. The messages with the

correct contents appear in the outbox, but it seems like the phone isn’t sending them. The

wiring is correct and the number to which the message should be send is correct too. If i go tothe outbox, “click” on one of these messages and hit “resent”, the message is send and appears

at my other phone after a few seconds. I don’t really know what i am doing wrong. If you have

any idea what the problem could be, would be nice if you could reply to my comment.

When it’s on.



It is the ‘end of file’ part of the command.

http://en.wikipedia.org/wiki/End-of-file

And I d on’t know how the phone will act if you try to send a text message over

140 or 160 characters. Try it out and see, it might depend on your carrier too.

And i forgot to ask: why do i have to use mySerial.write(byte(26)); //

(signals end of message) to end a message? Is it important how long the

message is?

Yea, i will try. Should i unplug and re-plug it while the phone is o n? Or while it is o ff?

Thanks.

I encountered this issue as well and unplugging the headset and plugging it back in seemed

to work.



You can put the serial parts in a f or loop, store you r nu mbers in an array, and do it that

way, otherwise I don’t know.

Everything works now, thanks for the great help. I have one last question: Is it possible to send

the message to more then one number?

Thanks again.

Sorry, I never ran into that issue myself so I can’t really suggest anything other than maybe

factory reset the phone and make sure it works by sending a test text message from it

manually.

Jeff Murchison Septemb er 15, 2013 at 10:17 am

It appears your include line is wrong. Use this instead:

#include < SoftwareSerial.h >

(remove the spaces around the < and > )

However, it does not go to messaing screen, but it goes to “Calls Made” screen. Could we

discuss how we can fix this?

Do you know what kind of sensors would be appropriate for such work? ( arduino

Absolutely. The code is ac tually very basic. I sugg est you read throu gh the code reference

material on Arduino’s website, and try out some of their tutorials. They’re very useful.

Hi thank you for such a great project!! i just had mine working and boy am i excited lol… I havea question though (and excuse my poor knowledge, im a newbie ).

Is there a way i could modify this circuit so that i doesnt use a pushbutton. Let’s say i want to

have the entire system self controlled and i want the arduino to send me a text message when

and only when something happens (i.e. the phone runs on low battery.) how can i do that. do

i need sensors, etc….

Thank you so much you are my new hero lol.

I’m using software serial on pins 2 and 3. The hardware serial pins are 0 and 1. The

software serial is for communicating between the phone and the Arduino, while the

Why did you use, the pines 2,3 ? my arduino have the tx,rx in the 0,1 pines. Thanks.

AT Commands are actually fairly standardized. You can control most mo dems with them

(even modern 3G or GSM modems).

The reason I used the headphone jack in this phone was because that’s where the serial

connection to the phone is. The only other jack on the phone was for power. Modern

phones typically won’t have a serial connection, let alone use the headphone jack for

anything other than mic / headphones.

If you find a phone that has a serial connection, then you can probably modify this project

for that phone.

This is pretty awesome. I haven’t tried the project, but I’m curious about why this works? I

suppose the commands “AT” etc. are specific for this Motorola phone (and some others)? Do all

phones have commands like this? As is, can the code be modified to do this through the

headphone/mic jack of any old phone? I had no idea phones could be programmed through

the headset jack. I guess you need insider knowledge about how the phone works?

It may be possible, but I’m not sure how to do it.

Hello! Thank You very much. I ordered a Motorola W375 for 1 Buck at eBay and 2,50€

shipping. It’s without battery, but I test out:

The 5 volts from the Arduino powers a cellphone. I hope that the phone will work

with external power. I’m planning to use

this as temperature monitor, giving statements

via SMS.
