Arduino Uno Parts Flashcards
this is how you power your Arduino when it’s not
plugged into a USB port for power. Can accept
voltages between 7 - 12V.
Power Connector
used for powering your Arduino Uno, uploading
your sketches to your Arduino, and for
communicating with your Arduino
sketch.
USB Port
use these pins to provide +5V power and ground to
your circuits.
GND and 5V pins
use these pins with analogRead()
Analog In
resets the ATmega microcontroller
Reset Button
these LEDs indicate communication between your
Arduino and your computer. Expect them to flicker
rapidly during skethc upload as well as during
serial communication. Useful for debugging.
TX and RX LEDs
use these pinswith digitalRead(), digitalWrite(),
and analogWrite(). analogWrite() works only on the
pins with the PWM symbol.
Digital pins
the only actuator built-in to your Arduino Uno.
Besides being a handy target for your first blink
sketch, this LED is very useful for
debugging.
Pin 13 LED
the heart of your Arduino.
ATmega microcontroller
indicates that your Arduino is receiving power.
Useful for debugging.
Power LED
These pins can be either inputs or outputs. Inputs
are used to read information from sensors, while
outputs are used to control actuators. You will
specify the directions (in or out) in the sketch you
create in the IDE. Digital inputs can only output
one of two values (HIGH and LOW)
14 Digital I/O pins (0-13)
The analogue input pins are used for reading
voltage measurements from analogue sensors. In
contrast to digital inputs, which can distinguish
between only two different levels (HIGH and LOW),
analogue inputs can measure 1,024 different levels
of voltage.
6 Analogue in pins (pins 0-5)
These are actually six of the digital pins that can
perform a third function: they can provide
analogue output. As with the digital I/O pins, you
specify what the pin should do in your sketch
6 Analogue out pins
