Arduino Uno 3

Six analog pins and give you access to an analog to digital converter or takes analog signals and converts it to digital signals.

• digital pin header

• analog pin header

• USB

• GND pin

Reboots the Arduino program almost instantly.

• USB

• GND pin

• power port(barrel jack)

• reset button

This LED tells you if you if the board has power.

• power on LED

• main IC

• TX RX LEDs

• voltage regulator

Blinks to indicate when the Arduino is receiving or transmitting data.

• reset button

• TX RX LEDs

• analog pin header

• digital pin header

Plastic line numbered from 0-13 and they give you access to the pins on the main chip. The pins act as inputs and read voltage or output applying voltage.

• GDN pin

• analog pin

• digital pin

• reset button

Pin used to ground a circuit. It gives you access to the lowest voltage on the board.

• voltage regulator

• GND pin

• power LED indicator

• power port(barrel jack)

The brains of the Arduino.

• power LED indicator

• voltage regulator

• main IC

• USD

Controls the amount of voltage that is let into the Arduino board.

• GND pin

• voltage regulator

• digital pin

• analog pin

A connection that allows you will load code onto your Arduino board.

• power port(barrel jack)

• voltage regulator

• GND pin

• USB

Terminates the power supply to the Arduino.

• reset button

• power port(barrel jack)

• GND pin

• voltage regulator
