Arduino Uno :- Arduino Uno is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It’s intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. it is easy to use even for beginners. Hugely popular, you will find numerous tutorials and build your favorite electronics project on Arduino uno. “Uno” means one in Italian and was chosen to mark the release of Arduino Software (IDE) 1.0.
The Uno board and version 1.0 of Arduino Software (IDE) were the reference versions of Arduino, now evolved to newer releases. The Uno board is the first in a series of USB Arduino boards, and the reference model for the Arduino platform; for an extensive list of current, past or outdated boards see the Arduino index of boards.
Arduino/Genuino Uno is a microcontroller board based on the ATmega328P (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started..
The following table describes the pins of the ICSP Connector.
|MISO||Master In Slave Out (Input or Output)|
|SCK||Clock (from Master to Slave)|
|MOSI||Master Out Slave In (Input or Output)|
|RESET||Reset (Active LOW)|
There is also a similar ICSP connector known as ICSP1 associated with the ATmega16U Microcontroller. For more information on this connector, take a look at the Arduino UNO Pinout image.
