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.

It turns out that the standard 8x8 LED matrix is not so easy to use because of all the wiring required and all the Arduino pins that are used - hence there aren't a lot of projects that use it.

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.

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.

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16 MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84 MHz processor, while augmenting inputs ...
