Eight Op Amp Circuits total – including such classics as: Inverting Amp, Non-inverting Amp, Summing Amp, Differentiator, Integrator, Differential Amp, Current Source, + a Buffer schematic thrown in for good measure.
Op Amp Pinouts
When you’re ready to build that operational amplifier circuit, swipe on over to the Op Amp Pinout Reference where you’ll find layouts for the most common single, dual, & quad op amp IC packages.
Show & Tell
Got a finished project you’d like to show off? We want to see it! Circuit Playground’s new Show & Tell section lets you easily snap a pic or choose one from your photo library, then send it to Adafruit along with your project description.
Touch schematic components to change values.
On any calculator that includes a schematic, you can now edit input values by tapping the relevant component symbol.
+ Additional improvements throughout
You’ll also notice a quite a few other tweaks and improvements added to make the app easier to use.
Version 1.5 is a free update for all current users – and as always, can be downloaded from the App Store. Thanks again to everyone who purchased Circuit Playground + all the helpful feedback & reviews – do stay tuned for more awesome!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
