Arduino Uno smd chip with cable

Arduino is the perfect board to get familiar with electronics and coding. Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards can read inputs–light on a sensor, a finger on a button, or a Twitter message–and turn them into an output–activating a motor, turning on an LED, publishing something online. We can tell the Arduino board what to do by sending a set of instructions to the microcontroller on the board. To do so, we need to use the Arduino programming language (based on Wiring) and the Arduino Software (IDE), based on Processing. While all Arduino boards differ from each other, several key components can be found on practically any Arduino.



1. Microcontroller – This is the brain of an Arduino, and is the component that we load programs into. Think of it as a tiny computer, designed to execute only a specific number of things.
2. USB port – used to connect your Arduino board to a computer.
3. USB to Serial chip – the USB to Serial is an important component, as it helps translate data that comes from e.g. a computer to the onboard microcontroller. This is what makes it possible to program the Arduino board from your computer.
4. Digital pins – pins that use digital logic (0,1 or LOW/HIGH). Commonly used for switches and to turn on/off an LED.
5. Analog pins – pins that can read analog values in a 10-bit resolution (0-1023).
6. 5V / 3.3V pins- these pins are used to power external components.
7. GND–also known as ground, negative or simply -, is used to complete a circuit, where the electrical level is at 0 volts.
8. VIN–stands for Voltage In, where you can connect external power supplies.
