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.

Each card includes information like voltage, pin diagrams, and more. They're incredibly easy to read and a great reference guide when you're first getting started with Arduino.

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 ...

You can use these pins with your projects. The Arduino Nixie Tube SHIELD is now available to back via indigo go with pledges starting from $25 and shipping expected to take place during December 2017.

Not long after [CulinarilySpeaking] got into the Arduino game, he began to want more IO pins and a larger program space for more ambitious projects. This, of course, led him down the path towards t… ...

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.
