Picture of ArduinoPhone

Combining Arduino and other shield modules, we make a mobile phone named Arduino Phone. Meanwhile, we printed a shell for it with the 3D printer. Although it’s not such fine as you think, even a little bit clunky, it’s still very cool. That is the point this is a cell phone made by ourselves.

While, we can’t install Arduino Phone Apps limited by Arduino. So, if you want to play Angry Birds, then you need to do some big modifications on Arduino Phone. :)

Next, I will make a detailed explanation about the steps of making an Arduino Phone, including the hardware connection and software implementation.

Now, let’s begin.

Step 1: Preparing stuffs

Picture of Preparing stuffs

At the very beginning, we’d better prepare the materials. Of course, most of these modules can be purchased directly, such as Arduino Uno, TFT Touch Shield and GPRS Shield.

Owning to we want to put our Arduino Phone into a 3D printed shell, and in order to adapt the size of this shell, we have to DIY a charging and discharging PCB board (including two parts) and an expansion PCB board which can connect to the headphone jack of GPRS Shield.

If you want to make a shell by yourself, you can directly take Lipo Rider, or something like this, as the charge sheet. Thus, you do not need to DIY PCB board in order to meet the size of the shell.

What you need:

1.Arduino Uno

2.TFT Touch Shield

3.GPRS Shield


5.Custom ArduinoPhone Charge Circuit (or Lipo Rider)

6.Li-po battery

7.A shell (with 3D printer)

All components at here.

Awesome project. Want to make my own, but here I can't find material I need.

Hey holidayy could u send me the code I got the calling to work and texting but it doesn't show the screen when I get the texts or calls yet I know it reviews them because of the fact that it plays a ringtone and it has a sign

Hey DJcoco15,

could you sent me your things which you used now for building your phone?

hey ForM4iN, the parts i used were very expensive and i hope to research and test other cut rate parts that are much less expensive but here is the current list of parts

1.TFT v2 seeed screen $20-$65 depending on the places you go you can find it inexpensive but if u go on the website its very expensive I used ebay

2. GPRS shield v2 seeed $20-$30 ebay

3. Lipo rider - seeed studio $8-10 only ont the website and ebay

4. Groove RTC -$7 seeed studio

5. cr 1225 and cr1220 batteries. 2-10 depends onhow much u get

lipo baterry 3.4 v i belive 2000 mah ill confirm with you on that. but you will need current - 10 bucks

solder u shuld havethis


3d printed or any kind of case

arduino uno

**** important******

this phone will work with any normal sized sim card no mini or nicro or any of that only normal and it needs to run on a gprs or gsm runned network i used AT&T you can get one for 10 with a contract

extra battery packs for current or 9v clip

I believe this is all ill gt back to u if i remember anything else

I am a german student at the gymnasium(academic high school).

I have to do a seminar thesis and there for i want to use the arduino phone.

Also i love to make something out of anything so :)

I have a sponsor so the money is fine.

So i want to do it good and thats why i ask you :)

Maybe you could sent me your code too somehow.

I also got a 3D-printer for the case.

But for now i really thank you!

So I got it working texting can get buggy though
holidayv DJcoco152 months ago

I have also had issues with the texting. I've had texts that don't send OR recieve and reading the texts is not reliable. You sometimes have to scroll back and forth to be able to read them. I like how you changed the colors. I have yet to get the RTC to work or the li-po rider. I really want to use the built in RTC on the GPRS module but can't seem to get it set. The li-po rider isn't outputting enough voltage. But these are minor items.

And regarding your gprs shield there are 4 gold circles these are the same as the rtc I will send the picture
Hey holiday I too had that problem with the lipo rider and I decided to use an extra 4-aa battery pack I might use rechargeable a for that but I used both at the same time and it worked well
Also the rtc I got soldered and it says 00:00 and it doesn't count so I'm working on that I'll get back to u if I get it working but also I've been thinking on adding applications such as the paint example and a calculator so if I get that working I'll give u that code aswell
And if u would like me to show you how I changed the colors I can show you
And with texting I have an external extra phone I used to activate the sim and I found that if they don't go through just delete the messages on the other phone because the problem is that there might be too much texts too handle at a time

great idea

great idea

DJcoco15 made it!2 months ago

So he was right change the jumpers and make sure you change the tft library to tftv2 and change tft.init to tft.TFTinit

Btw i changed some aspects and srry for thebad spelling

holidayv made it!2 months ago
Here's mine. I had to adjust the code for the newer models of GPRS shield and TFT display. Make sure the jumpers on GPRS shield are set to hardware serial.
holidayv2 months ago

I have it built. I have solved the problem with using the 2.0 TFT. My SIM card is activated. It won't make or recieve calls or texts. Looking at the code, it does not appear to include either the GSM or GPRS libraries. How can it make calls???? I've dumped over $100 into this only to have it NOT WORK! Has ANYONE gotten this fully functional in the US?

JohnyB1 holidayv2 months ago

I also have this problem, I can not make calls or send text. The ArduinoPhone receive call but I can not accept it because the UI for receive call is not showing. Any idea how to solve this problem?

holidayv JohnyB12 months ago

I got it working tonight! Switch the jumpers of your GPRS card to hardware serial instead of software serial and all of a sudden....It works!

holidayv JohnyB12 months ago
I think the problem is in the AT commands. This project was developed in China which uses a different AT code than North America. Going to work on it this weekend and see if i can get it working. If I can, I'll post the corrected code for North America
holidayv JohnyB12 months ago
if you are receiving calls, you are better off than me. Mine will not send or receive calls or text. I'm really irritated by the fact that it seems to be more of an instructable on 3D printing the case. Very little instruction on the actual device. Also, i purchased the li-po charger and it only outputs 2.6v off the USB when running on battery power. The link for "more information" is just another web page with the EXACT SAME information. Very irritating.

I have built an Arduino cell phone using a T-Mobile SIM here in the U.S. It is primarily used for receiving text messages to trigger a servo motor but it can also make and receive calls. You can download the Arduino code here. The only issue you may run into is I have not had time to port the code to the latest Arduino dev environment so this code uses the Arduino 0022 release. Here is the code address:

useful information

Is the chipset Android compatible? Even if it were only able to run Android 2.3 or something, that would still be awesome! How thin a device could you make with this? I would like to make an Android wrist-band GSM phone with this same 2.8" screen. Adding in GPS and WiFi would be great. Is it necessary to be Arduino-literate? Are there alternative methods to, say, flash an Android OS onto the chip with a PC?

great one;

very nice:)

Can i use a sainsmart 3.2 TFT for this?

torivc5 months ago

Where do i place the file? After installing the other libraries in the proper arduino library folder and restarting. I'm getting this error:

'Tft' was not declared in this scope
Pls let me know what i'm missing. Great project. Btw

It is very great project.

I want to make a your project but dont understand codes.

If the next sentence description of your code if you could write?

Thanks for the instructions and code! I modified this project just a little bit. I used the same hardware and integrated it with an old rotary phone. It's the world's first rotary cell phone! See my blog entry about the creation here:

Could you make available the 3D printer files for the "box"?

Hey Buddy.. I absolutely love and appreciated this project you've come up with.

I've used and Arduino UNO rev3 and stacked the GPRS shield v2.0 (By seeedstudio). Everything else is exactly the same way you have shown.

I connect the UNO, it is bring recognized, I upload the code, it gets successfully completed. But for some reason, I always get a constant blank TFT screen instead of a menu..

Any help please ???

I am getting the same problem as well, I have updated the software from Seeed Studio's site and it is still blank and not working at all. Does the ENTIRE circuit need to be complete or can you and everyone else still get the interface and UI regardless?

use the good library, you probably have the v2 of the TFT, just get them from seeed studio site and replace.

The code will not upload at all, as is! I get expected primary expression before "." token type of error.
