PLEASE NOTE: the app is now updated to work on Android 4.4 (and newer) devices.

Arduino Companion is an app for designed to help anyone getting into Arduino and electronics. The app contains the full Arduino Reference for offline use, as well as a handy resistor calculator. The Reference contains all of the basic Arduino reference, but it also covers all the included classes for controlling Ethernet, Servos, Serial Communication, LCD Displays, SD cards, Keyboard and Mouse (Leonardo) and more. Now also covers Arduino Due.

Feel free to contact me to suggest features you feel is missing or if you find any bugs. Contact me using the About-page inside the app or the email listed below so I can fix the issue.

Whats new

    Version 1.3.1 changes:
    - Scaling updated to work better on high-resolution devices
    - Tap on title to scroll to top
    - SSL security fix
    If you experience a bug, please leave a message via the app or the listed here. I'm curious to know if the scaling works well across devices. If it looks terrible on your device, please send a screenshot to the email below.

Update: Be I originally gave this 2 stars because the font was too small on the S5. The dev sent me a message that said it was fixed so I downloaded it and it works well now. The only problem I have seen so far is that some links will end up bringing up the Arduino website. For example if I look up shiftOut() it has a link to the SPI library documentation. When I click it I expect the SPI documentation in the app to pop up but instead it takes me to the Arduino website. That is the only instance so far after playing with it for 10 minutes that I have seen. Not end of world sort of problem and it does take me to the correct webpage.

More libraries pls Please, add more libraries from adafruit for example or other brand shields or give a way to add our own libraries - tkx


Thanks Very helpful for beginner such as myself. Clean, simple layout. Thank you.

David Haley

Updated! Font size update makes it a lot easier to read. Now if you can just make the title bar and the bottom menu bar either shrink or disappear in landscape mode that would make it really good.

Kaz Z

Very usefull. Well srtuctured. For offline use.

Craig Faas

Perfect A perfect reference tool for Arduino. Nice Job!

Jobayer Arman

Just as I needed Well Structured and highly readable than any other app available. Keep updating it with more content.

Rohan Baidya

descriptive enough up to need.

Ian K

Hurray! Used an older version but when I changed phones it no longer worked! Now it's working and I'm happy to have this resource back!

Ryan Spencer

Works Flawlessly Very good app. Nice built in resistance calculator/identifier. Great for offline help or as a quick reference. Developer cares about users and his apps reviews/comments.

Scott McIntosh

Outstanding dev support The developer contacted me via Google and asked me to check out the app. It installed perfectly and runs great. Very useful and I am impressed with his response!

Jesse Newell

This is the Ardruino companion! I have to say, this app is very cool! So handy for when you are without Internet access and wanting to program.

Alan Nudi

Convenient Works well, and could use some visual updates (text is too small on nexus 5) but it does it's job. Gonna use it a lot more now.

Ivan Rosales

Look no further! This is the one and only offline Arduino language reference, this app worth it's weigh in gold.

Mapi Pato

Well,screen resolution seems to be an issue,but u can find a lot of usefull information there.

Tendy Ikpe

Lovely App The app is very lovely especially the resistors calculator, that feature is very important to have. Weldone developer. Thanks for the wonderful work.

Thomas Pfaff

Thanks Thanks! Consider making it available through f-droid too ;-)

João Melo

nice very useful app and great support :)

Monty Fox

Menu text too small The menu text is WAY too small on an S5. It's almost unreadable. However, once you make a selection the size of the text is fine. If this was fixed I'd give 5 stars.

Zaahied Cassim

It does what is says...Companion Refreshing to finally load an app that delivers the goods...a thank you to the developer

Scott Loudon

Perfect off line resource . It's a great reference, I tend to put to much time in between projects, this works better than my memory.

Shane Denomme

Finally Fixed! I can finally change my review to a real one. This app is great, it's the only available offline reference I can find and the mobility it grants is also a plus. The Resistor calculator is also very cool. I also would like to thank the developer for sharing this awesome project, keep up the good work!

Antony Furneaux

Yay working again on my nexus 7 Thanks for the update.

Sumit Bhumbak

By The Bhumbak Really useful app

Michael Droll

Awesome resource I changed the rating after this last update, it now works! The ui scale is really small and can be difficult to tap what you want. But overall a solid app and a must for arduino.

Parag Naik

Now working on Android L App now working for Android L

Gresanu Emanuel

Very useful for beginers in arduino.

Steve Hughes

Good reference. Can't rate 5-star because of the butchering of the English language.

J Anderson

Great application I am a programmer who is starting to play with Arduino. This app is very handy. If I get an idea to test out it is nice to be able to just grab my phone and plug instead of pulling out the laptop. So far everything works great. Thanks for the wonderful application.

Trey Mondo

Very good for reference

richard chiwara

awesome this app is great...cant even go to work!!!!

Miguel Manuela

Great app definitely download for arduino users Great app, only an upgrade for 4.4 would do the 5 star rate. Then I can use it on my othee device as well. Also your I think you should ad some simple electronic schematics with explanation of the code of how it works. So you can see how the different lines of code work. This would be great especially for beginners. Futhermore great job! ;-)

Chris Norris

Handy A well thought out and useful app with easy to find arduino language references.

A Google User

very good .. A neat program that gives you complete control over every command, variable, function, etc in arduino.. kudos.. ps: would be nice to be able to search for the command you need help with, instead of going thru the menues..

Maxim Eagle

Very slow interface :(

Max Kryazhev

Languge Please Russian languge. Very need.

Walter Red

From function description app dn't return to functions list when you press Reference button

Пользователь Google

Prerequisites Requires adobe air

Javier E

Best option up to now I am using it to read with no internet or it also will be nice as a quick reference guide... Thanks

Ivan Rosales

Look no further! This is the one and only offline Arduino language reference, this app worth it's weigh in gold.

Johnny Spangler

Amazing. Extremity helpful for both a beginning and an experienced arduinoite

Alexandru Corneliu Moldovan

Not very useful If you have programmed Arduino earlier, this guide won't help you so much. Quite basic.

John Maffysdad

Is a very good reference source. There are many Arduino apps out there that try to be helpful to newcomers to the Arduino, even, and whilst this take information that is on that site, it words it such that this one is easily one of the better ones to understand. It lists useful information, keywords with brief descriptions & code, it isn't in depth, but suffices more than enough to gain good a good working knowledge in offline mode. Thank you :-)

Britt Bush

Great Even though it has a copy and paste feel from the online arduino reference, it's very well organized and makes looking stuff up a breeze. Fantastic for a free app!

Justin Valois

Great reference Does what it says it will.... Of course I think a fewe app should have reference for all languages, then id give it TEN STARS. But since it doesnt, Im really upset. (Some people have a lot of nerve) 1 star? Really?

Steve Perkins

Excellent app Simple to use, great reference, no ad nonsense. Thanks Jens.

Steven Chan

Zoom in zoom out Android doesn't need this button. Its covering text and useless button

Electronicbrain Kid

Extremely Useful! This app is great for begginers to learn basic commands, or just a quick lookup when you forget one!

Malcolm Bannister

Brilliant App I'm new to Arduino and this is my goto reference. Thanks Jens. I'll give you ten stars! Brilliant! **********

Tikki Bear

Very nice and handy! Hey Jens, I think it would be nice that you should add pin reference in to this app too.

Sasanka Kuruppuarachchi

Finally... :-) Thanks a lot guys. This is like gold to me.

anilkumar sastapure

Thanks for considering my request GSM library info is missing please add it

Mr. McKinney

seems excellent to me', worth every penny :[) lol
