Yesterday, Google announced their open accessory kit based on Arduino. Although they aren’t immediately available for sale in the US, they (or something like what you see in this post) will be soon. Also, the design files are available as part of the ADK, which you can download from here.
NOTE: My understanding is that this is based on the [email protected] USB Host Shield. If anyone out there has one of these shields, I’d be really interested in hearing in the comments whether the sample app Just Works for you. You’ll need to wire up the sensors and actuators used in the demo kit, but many of these are simple (buttons, LEDs, relays).
Google gave away a few hundred of the kits here at Google I/O 2011, and I got my hands on one. Inside the box are two sub micro servos, a shield that’s loaded with buttons, LEDs, relays, and more. And the board itself is based on the Arduino Mega design, with the USB host module added (this means that there are two USB ports: one to connect to the Android phone, and the usual one to connect to your computer for programming/serial monitor access)…
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.
