Session - 6

ARDUINO UNO BOARD


Introduction of Arduino

• Arduino is an open-source hardware and software platform designed for


computer programmers, professionals and those interested in developing
interactive devices and applications specific to an interactive development
environment.

• Arduino can receive input signals from various sensors and inputs.

• Arduino is able to run independently or communicate with software


running on a computer (for instance, Flash, Processing and MaxMSP).
Introduction of Arduino UNO

• Arduino Uno is a microcontroller board based on the ATmega328P .

• 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.
