When writing about the Beaglebone in the past, I mentioned that you needed to be running Angstrom in order to have access to certain devices, since they weren’t yet supported by the kernel in Ubuntu.
Well, I’m rather late in giving Ubuntu its props, but that’s no longer true. Ubuntu has caught up to Angstrom in protocol support: analog input, PWM, SPI and I2C are all working.
In order to get these features, you need to have a recent kernel. I’m not sure exactly which kernel version they were added in — 3.2.twentyish — but current kernel version for Ubuntu is 3.2.28. If you’re running an earlier kernel, I’d recommend that you upgrade.
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.
