Anyone with more than a passing interest in building electronics will be familiar with Arduino and the projects that can be built using this popular platform.

If you’re not too familiar with what we’re taking about; Arduino is an electronics platform that provides the software and hardware to help users build electronic gadgets and interactive prototypes.

If you are considering purchasing an Arduino in Australia, there are a few options available to choose from, the newest of which is the Arduino Leonardo.
As it’s a new addition to the Arduino family, we’re about to tell you four main differences between  Arduino Uno and Arduino Leonardo.

1. Digital pins

An Arduino Uno has fourteen digital pins whereas an Arduino Leonardo has just four additional digital pins.

A Leonardo has the same fourteen digital pins as an Uno but it also has four extra pins, which are mapped to its ICSP header.

The fourth pin is not mapped anywhere on the ICSP header and you must connect a wire to either the end of the Rx LED or the other wire attached to it.

2. PWM pins

The Arduino Leonardo has seven PWM pins while the Arduino Uno has just six. And if you’re thinking that one additional PWM pin doesn’t seem all that important, the timers on a Leonardo version are of a higher quality.

There are 3 timers – an 8-bit timer, two 16-bit tiers and a 10-bit high-speed timer.

3. Analog pins

With an Arduino Uno, there are six analog pins that, by the way, can also be used as digital pins. On the other hand, Arduino Leonardo has twice as many with twelve in total, all of which can be used as digital pins too.

It’s important to remember that with current Arduino shields, analog pins are positioned among the digital pins and are marked with a dot on the topside of the board with numbering written on its back.

4. Keyboard and mouse emulation

The main difference between an Uno and a Leonardo is that the Leonardo supports USB directly which means that it can operate as a USB device such as a computer mouse or a keyboard.

Arduino makes it easy to create this functionality by creating a Mouse class and a keyboard that teaches you all you need to know about creating both projects.

Both Arduino Uno and Arduino Leonardo are top of the class with very little to separate them. Both offer an excellent electronic experience and are easy to work.
 
That said; if you are interested in a platform with built-in USB, a Arduino Leonardo is the one for you.
