Reasons to pick the Arduino Mega
With the Arduino Mega, one of the larger more commonly used Open-source Arduino boards. Start any electronics or coding projects readily available online in the huge Maker community, or design a project yourself.

The Arduino Mega hosts a very large amount of Digital I/O connecters, a quick reset button, and machine screw holes to mount the board however you please. Using the ATmega2560 microcontroller, this board allows great control over a huge amount of components and devices, and gives you have enough power and memory to store and run lot of complex code.

The best bit about the Arduino Mega is that if you choose to use a shield you can still access a large range of I/O pins for further use with other devices like individual components, break out boards, or even expand further into a breadboard.

Connections and Expansion
This board hosts a humongous amount of Digital I/O pins, 54 in total, 15 of which support PWM. 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, it will be difficult to push this board to its limits.

The Arduino Mega also supports 16 analogue inputs, allowing for use of a large range of sensors. Analogue sensors allow you to make your own smoke detector, tell if a plant has enough moisture, to detecting if something has triggered a pressure mat, or all of them, with even more sockets to spare.

The Arduino Mega can use standard shields based on the Arduino Uno R3 layout, as well as being able to incorporate the much larger shields which are specifically designed for this board.

What will you make?
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.

A great range of accessories are called breakout boards, tiny shields that link together just as easy as shields usually providing more specific uses. Arduino shields come in many shapes and sizes, from providing solder-able break out boards, a 1.8" TFT screen with micro SD slot and joystick, to a servo and motor control board.

Shields and Breakout boards allow you to more easily manage a lot of components in any project, you can view our range of shields and breakouts by clicking here.

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.

Start by;
Making an LED Blink,
design your own Mood Light,
or if you’re feeling brave, make a mega clock.
