Circuit Playground

Found this app to be an excellent reference for my hardware projects. Clean, simple, with lots of spec info for simple circuits. Would like to see more pin layouts for more boards but great resource as it is now.

I mainly got this for the resistor codes but I have no doubt I'll put the other tools to use too. It's a nice little app and I'm happy to support Adafruit software!

Much more convenient than searching the Internet and handy when checking all kinds of things like USB connector pinouts.

I use this app everyday. To say that the resistor and capacitor value tools are useful is an understatement! Lately I have been looking for an application that features a function generator. -nothing too complicated. Two channels independently able to output sine, square, sawtooth, triangle signals all with adjustable amplitude and frequency, and maybe a little noise would be perfect! There are a few out there, but their interfaces seem to be slightly less than elegant. Besides that, I would much rather support the crew at Adafruit whose quality I can trust! -just a suggestion. :)

I use this app almost every day. Particularly useful is the number converter for allowing me to quickly lookup I2C addresses, and then shift the bits for the read/write so that I don't have to do the HEX in my head. Also use it for basic conversion when understanding register values, as it's handy to have right on my phone. I like the LED calculator, and the resistor/capacitor codes, but I'd like to see a simple voltage divider calculator and even a logic gate tool with truth tables for NAND/AND/NOR/etc functions. Overall, very cool. Definitely gives me some additional, but un-needed, geek cred.
