Arduino-compatible ATtinys with more pins Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate ...

So if you’re knee deep in an Arduino-based project and you want to constantly monitor all of the micro’s pins, what’s the best way to go about it? [Jonathan Clark] from LVL1 in Louisville ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led - the green one on the left in the photo.

The basic functions of the Arduino IDE – pinMode, digitalRead, digitalWrite, and analogRead – are available. Most of the WiFi functions work just like the WiFi shield library.

The UDOO contains both and ARM cortex-A9 CPU and the hardware on a Arduino DUE. This includes 54 digital I/O pins, an optional SATA connection, and a number of other pin-outs and connectors.
