The hardware tinkerers and prototype mavens out there will invariably have stumbled across the Arduino platform. Completely open source and always pushing the limits for collaboration, there are a ton of different development boards available, but none are as awesome as Johan Kanflo’s AAduino. Behind the delightfully punny name, you’ll find an Arduino-compatible board the size of an AA battery.
Growing up in the bad old days, you’ll remember what an epic pain in the rear-end it used to be to get started with electronics and embedded circuits. That all went away when the Arduino team sprinkled a generous helping of user-friendliness across the proceedings, making it easy to (re)program the processors, and using a Java-clone and an easy-to-learn IDE made it ridiculously easy to develop software for hardware applications.
Based on the Tiny328, AAduino takes the platform to its sexiest form factor yet: Turning a three-AA battery holder with two batteries in it — the third battery compartment holds the AAduino — into a powerful, yet diminutive computing platform that fits in the palm of even the smallest hands.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
