Arduino Uno

One of the most popular Arduino boards out there is the Arduino Uno.  While it was not actually the first board to be released, it remains to be the most actively used and most widely documented on the market.  Because of its extreme popularity, the Arduino Uno has a ton of project tutorials and forums around the web that can help you get started or out of a jam.  We’re big fans of the Uno gbecause of it’s great features and ease of use.

Board Breakdown

Here are the components that make up an Arduino board and what each of their functions are.

1. F – Stands for “Analog Reference” and is used to set an external reference voltage
2. Ground Pin – There are a few ground pins on the Arduino and they all work the same
3. Digital Input/Output –  Pins 0-13 can be used for digital input or output
4. PWM – The pins marked with the (~) symbol can simulate analog output
5. USB Connection – Used for powering up your Arduino and uploading sketches
6. TX/RX – Tra
7. Reset Button – This will restart any code that is loaded to the Arduino board
8. ARE
9. nsmit and receive data indication LEDs
10. ATmega Microcontroller –  This is the brains and is where the programs are stored
11. Power LED Indicator – This LED lights up anytime the board is plugged in a power source
12. Voltage Regulator – This controls the amount of voltage going into the Arduino board
13. DC Power Barrel Jack  – This is used for powering your Arduino with a power supply
14. 3.3V Pin – This pin supplies 3.3 volts of power to your projects
15. 5V Pin – This pin supplies 5 volts of power to your projects
16. Ground Pins –  There are a few ground pins on the Arduino and they all work the same
17. Analog Pins –  These pins can read the signal from an analog sensor and convert it to digital
