Circuit Playground – Adafruit’s iPhone & iPad app for electronics + more…

Playground

“Very useful “by MakerMaker5 star reviews!
Incredibly handy for anyone working in electronics. Perfect for engineers and non-engineers alike.

“Just what this hobbyist needs” by JoshuaUnwin5 star reviews!
I love the clean look and focused tools in this app. It has earned a spot on my first home screen…

Circuit Playground simplifies electronics reference & calculation so you can have more fun hacking, making, & building your projects! This app is designed for both iPhone and iPad.

  • Decipher resistor & capacitor codes with ease
  • Calculate power, resistance, current, and voltage with the Ohm’s Law & Power Calc modules
  • Quickly convert between decimal, hexadecimal, binary or even ASCII characters
  • Calculate values for multiple resistors or capacitors in series & parallel configurations
  • Store, search, and view PDF datasheets
  • Access exclusive sneak peaks, deals & discounts at Adafruit Industries

All that, plus updates with additional features & enhancements – MANY NEW CALCULATORS AND TOOLS being added! Not on iOS? An Android version is in the works :) For now, if you’d like to support a cool Android app and developer check out ElectroDroid. Please scroll down here and watch the HD video below about Circuit Playground and check out the screen shots!

  1. Adafruit does it again! COOL!!!!

  2. Good move suggesting electrodroid for Android. That is cool stuff.

  3. The other day a guy on the Netduino forum had a good suggestion for an app: Make an app that would use the camera to decode resistor values.

    This would be useful for the color-blind as well as people who are just getting older.

    You should add this to your cool app. It doesn’t seem easy – but it doesn’t seem impossible either.

  4. I second Yankle’s comment! Very cool indeed!

  5. I love the elegant interface. No clutter. Adafruit you have hit on your hands but you probably know that already.

  6. Great interface and it works on my iPad and iPhone.

    Surprised no one mentioned the Circuit Playground app is essentially free. I see the discount code for my next Adafruit order is the cost of the app! Very clever Ladyada :)

  7. This seems identical to circuit sidekick. Can I assume the new features will distinguish it?

  8. @aaron, that was the previous version of the app. collin worked with us to update the app with new features, new calcs, new interfaces and more.

  9. I agree with Dan. Being colorblind, it makes it difficult to decipher resistor color codes. Being able to use the camera would greatly simplify things.

  10. I have a non-english locale on my iPhone that has commas as decimal marks. I discovered that I need to turn of Comma Delimiter in the app settings to make calculations correct. Results where of by a factor of 1000, unless the input values were less than 1000.
    A fix could be to remove the Comma Delimiter option for users with a locale that has commas as decimal marks.

    Would like to have an even faster resistor color values function. The current solution where the view slides back and forth between the overview and the individual colors gives less overview than adjusting all values on the very same screen. Your solution for the comment CAPTCHA is great. Other apps uses some kind of scrolling wheel, which I find very intuitive and provides great overview.

    Otherwise a great app. Love the Ohm’s Law triangle calulator!

  11. great feedback carl, thank you!

  12. I noticed a bug on the multiple resistor calculator.
    If you select parallel, and then switch to one of the other calculators, when you come back to the resistor calculator the formula at the bottom is wrong (shows the formula for series, even though the diagram is parallel).

  13. @greg, huh – we did not see that, but we will check it out – thank you! iphone or ipad and which OS version if you happen to know as well.

  14. iPad version, 5.0.1

  15. For what it’s worth, the same thing happens on the “Multiple Capacitors” calculator as well. And the calculations are actually wrong as well (they’re done with the formula at the bottom, which doesn’t match the diagram or the option selected in the corner). I can send you screenshots if you’d like.

    (update from adafruit* calculations are correct as per greg).

  16. @greg – we’re all set, this is logged in – thank you!

  17. Wow! This app looks really interesting. Unfortunately, I can’t load it on my iPod touch because it requires iOS version 4.3. (I’m running version 4.2.1, and version 4.3 is the first release that is not compatible with my 2nd generation iPod touch).

    Is there a technical reason for this version requirement? If not, I hope you consider releasing an update that is compatible with version 4.2 (or lower).

    Thanks. And once again, great work.

  18. Thanks for logging that. Also, the calculations are actually correct, I was incorrect on that observation.

  19. Fantastic App geat tool

  20. Bought it. Look forward to checking it out. Thanks!

    From my pocket to yours! :)

  21. This is bloody fantastic. I am so grateful and proud!

  22. I’ll second Adam F’s request for iOS 4.2 support. I have an old iphone I use as my personal diy assistant. I don’t want to spoof my iOS version unless I have to ;)
