The other day, we gave you an overview of the Yún’s hardware. Today, we are going to talk about the Bridge library, describing how it facilitates communication between the two processors. The Arduino Yún has two different processors on-board: an Atheros AR9331 running Linino (a customized OpenWRT GNU/Linux distribution maintained by Dog Hunter) linked through its serial port with an Atmel ATMega32U4 (the same processor as the Leonardo).
Coming soon! Arduino YÚN. Arduino YÚN is the first member of a new groundbreaking line of wifi products combining the power Linux with ease of use of Arduino. The first Arduino YÚN is the combination of a classic Arduino Leonardo (based on the Atmega32U4 processor) with a Wifi system-ona-chip running Linino (a MIPS GNU/Linux based on OpenWRT). We embedded the Linux machine directly on the PCB of the Arduino Leonardo and we connected the two so that from Arduino it’s very easy to run commands on the Linux side and use it as an Ethernet and Wifi interface.
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.
