The Arduino- an affordable, open source microcontroller board- has been touted as connecting the real world to your computer (a few Arduino projects: a battery life extender; a DIY Water meter; a tweeting; self-watering garden system; an open energy monitor; a sun-tracking solar panel). We talk to Arduino co-founder Massimo Banzi about the power of the Arduino, how it’s “not for nerds” and how it was kept alive by the fact that it was open source.
The last part — specifically how Arduino stayed alive by being open source — makes an interesting point about the potentially short life-cycle of closed hardware.
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.
