If you’re new to the world of the Arduino Uno – and the many projects and applications possible, using it – you may be wondering exactly what sets it apart from competing models of different boards available in the industry. Let’s take a look at some specifications that set the Arduino apart, and what makes it so versatile.
The Basics
Based on the previous ATmega328 board, the Arduino Uno is a microcontroller board that can be powered by a variety of sources and can be used for an almost innumerable number of applications. It comes equipped with all the components necessary to support its microcontroller function. These components include:
- Fourteen digital input and output pins (Six of which can also function as PWM outputs)
- Six analog inputs
- A 16 MHz ceramic resonator
- A USB connection
- A traditional power jack
- An ICSP header
- A reset button
Dubbed the Uno – meaning “one” in Italian and several other languages – this model of the Arduino is the first and the starting point for all later versions.
Recent Updates
There have been two more recent versions of the Arduino Uno, both of which came with technological updates to make use easier and more conducive to creating than ever.
Version Two –This version boasts a resistor pulling the 8U2 HWB line to ground, which makes going into DFU mode easier for users.
Version Three – This update features a stronger reset circuit. Atmega 16U2 has also replaced the 8U2.
A popular microcontroller, the Uno and subsequent models have a large, international fanbase. Look online for many forums and groups dedicated to the creation of great projects with an Uno at their heart!
