A more interesting segment for us is what we call Derivatives. These are products that are derived from the Arduino hardware design but they innovate either by providing a different layout and features often to better serve a specific market. These are the products that have also helped Arduino become so ubiquitous.
There are many examples but I will mention only a couple:
Teensy by PJRC – Paul has contributed a lot of code, bug reports, pull requests and to the discourse in general. Flora by Adafruit – Limor has contributed over 100 libraries and countless tutorials about Arduino becoming one of the most important members of the Arduino ecosystem.
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.
