Arduino Micro Board

• Start your electronics and coding projects with the user friendly, open source Arduino Micro
• Header pins allow you to snap this into any breadboard
• Power your Arduino with just a USB cable
• 20 Digital I/O Pins to control a vast range of components
• Using Arduino has never been easier, with thousands of tips, tricks and guides readily available online.

Reasons to pick the Arduino Micro?
The Arduino Micro, a tiny open-source Arduino board. Start any electronics or coding projects readily available online in the huge Maker community, or design a project yourself.

With any tiny project, you’ll need a tiny board, none will fit better than the Arduino Micro, being only 18 mm wide it can be tucked into the tiniest of places. The Arduino Micro, despite its size, provides you a great amount of I/O pins to work with, as well as a quick reset button.

Among all the other great features, the best thing about the Arduino Micro is that it is breadboard ready, it sits across any breadboards divider. Using the Arduino Micro with a breadboard allows you to immediately start prototyping any project, without the fuss of soldering or bridge out to a secondary board.

Connections and Expansion
The Arduino Micro has 20 Digital I/O pins allowing you to individually control a large amount of components. Each of the Digital I/O pins can control a limb for a walking talking robot, control hundreds of RGB LEDs, or build your own keypad controlled electronic door lock, and so much more.

Something quite unique about the Arduino Micro is the large amount of analogue pins, 12 in total. Analogue pins are great for sensors, these could include photosensitive resistors, potentiometers, or even make your own analogue sensors.

Where the Micro doesn’t support shields, it can utilise break out boards, which are like tiny shields that link together just as easy, usually providing more specific uses. Breakouts allow you to more easily manage a lot of components in any project, you can view our range of breakouts and other Arduino accessories by clicking Here.

What will you make?
The Arduino Micro is small enough to be incorporated into a wearables project. In recent years wearable technology has caught a lot of attention and is vastly expanding and growing in the Maker community. Wearable technology can be crazy, kooky, and fun, as well as helping us to make our work and lives easier through greater communication and increased functionality.

With the ever expanding range of tutorial guides available, you can start by telling a single LED to flash, or control a stepper motor’s speed and direction. Using coding languages called C/C++, these skills easily translate to most general software languages, and so with this you’ll be learning a lot more than electronics.

Ease of Use
Arduino is fantastic for all ages, whether you have previous experience or not, from fun to functional. Tutorials will tell you exactly what you will need, even what pins to connect your components into, giving you a step by step, start to finish.

Using the Arduino IDE Software, it will allow you to very easily update your Arduino board with the code you’ve prepared, making the transfer seamless, it will even let you know whether your code makes sense and will work before you even upload it.

Make the most from your Arduino Micro, start by;
using a Bargraph with a microphone to determine sound levels,
or even make your own Keyboard and Mouse controller.

Arduino IDE software is needed to program an Arduino, it’s not in the box. Download from here:
Works on Mac, Windows and Linux based computers including Raspberry Pi's Rasbian software

Is it possible to power it using something other than a USB chord, like with some kind of adaptor.

Asked by: Edward
Sure, there is pin that can be used to power the board. It can actually be used at the same time as the usb cable as it will automatically use the higher voltage. Check the max voltage though in the datasheet (I think<12V).
