What's New in Circuit Playground

2.1.5

September 3, 2021

Improved support for iOS 14

User reviews

Has useful stuff

Some handy knowledge is present, but some other entries could be added for rf/si topics quite readily

Really good, wish they’d update

The little calculators are great, especially for beginners. I wish they’d update it, though.

Not what I expect.

Very disappointed, so requested an immediate refund. Why did I buy it?

Need to update USB TYPE C

Probably a few other updates are needed.

Almost

Does not let me decide which values must be fixed and which must be computed, and usually gets it wrong, requiring much fiddling to get the answer desired. Does not have a way for handling LEDs in parallel. Otherwise, really useful piece of software, especially for teaching.
